Disable setting the MII port speed.
This seems to break at least my test board here (AR71xx + AR8316 switch PHY). Since I do have a whole sleuth of "normal" PHY boards (with an AR71xx on a normal PHY port), I'll do some further testing with those to determine whether this is a general issue, or whether it's limited to the behaviour of the "fake" dedicated PHY port mode on these atheros switches.

Break out the arge MDIO bus code into an optional argemdio device.
This is only done if the ARGE_MDIO option is included.
* Shuffle the arge MDIO bus into a separate device, that needs to be probed early (use hint.argemdio.X.order=0) * hint.arge.X.mdio now specifies which miiproxy to rendezvous with. * Call MAC/MDIO bus init during MDIO attach, not arge attach.
This is done regardless:
* Shift the arge MAC and MDIO bus reset code into separate functions and call it early during MDIO bus attach. It's required for correct MDIO bus IO to occur on AR71xx/AR91xx devices.
* Remove the AR71xx/AR91xx centric assumption that there's only one MDIO bus. The initial code mapped miibus0(arge0) and miibus1(arge1) MII register operations to the MII0 (arge0) register space. The AR724x (and later, upcoming chipsets) have two MDIO busses and the second is very much in use.
TODO:
* since the multiphy behaviour has changed (where now a phymask of >1 PHY will still be enumerated), multiphy setups may be quite wrong. I'll go and fix these so they still have a chance of working, at least. until the switch PHY support appears in -HEAD.

Fix link status handling on if_arge upon system boot to allow bootp/NFS to function.
From the submitter:
This patch fixes an issue I encountered using an NFS root with an ar71xx-based MikroTik RouterBoard 450G on -current where the kernel fails to contact a DHCP/BOOTP server via if_arge when it otherwise should be able to. This may be the same issue that Monthadar Al Jaberi reported against an RSPRO on 6 March, as the signature is the same:
%%%
DHCP/BOOTP timeout for server 255.255.255.255 DHCP/BOOTP timeout for server 255.255.255.255 DHCP/BOOTP timeout for server 255.255.255.255 . . . DHCP/BOOTP timeout for server 255.255.255.255 DHCP/BOOTP timeout for server 255.255.255.255 arge0: initialization failed: no memory for rx buffers DHCP/BOOTP timeout for server 255.255.255.255 arge0: initialization failed: no memory for rx buffers
%%%
The primary issue that I found is that the DHCP/BOOTP message that bootpc_call() is sending never makes it onto the wire, which I believe is due to the following:
- Last December, a change was made to the ifioctl that bootpc_call() uses to adjust the netmask around the sosend().
- The new ioctl (SIOCAIFADDR) performs an if_init when invoked, whereas the old one (SIOCSIFNETMASK) did not.
- if_arge maintains its own sense of link state in sc->arge_link_status.
- On a single-phy interface, sc->arge_link_status is initialized to 0 in arge_init_locked().
- sc->arge_link_status remains 0 until a phy state change notification causes arge_link_task to run, notice the link is up, and set it to 1.
- The inits caused by the ifioctls in bootpc_call are reinitializing the interface, but not the phy, so sc->arge_link_status goes to 0 and remains there.
- arge_start_locked() always sees sc->arge_link_status == 0 and returns without queuing anything.
The attached patch changes arge_init_locked() such that in the single-phy case, instead of initializing sc->arge_link_status to 0, it runs arge_link_task() to set it according to the current phy state. This change has allowed my setup to mount an NFS root successfully.

Correctly (I hope) deallocate the if_arge RX buffer ring on arge_stop().
I had some interesting hangs until I realised I should try flushing the DDR FIFO register and lo and behold, hangs stopped occuring.
I've put in a few DDR flushes here and there in case people decide to reuse some of these functions. It's very very likely they're almost all superflous.
To test:
* Connect to a network with a _lot_ of broadcast traffic * Do this: # while true; do ifconfig arge0 down; ifconfig arge0 up; done
This fixes the mbuf exhaustion that has been reported when the interface state flaps up/down.

- Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP (reporting IFM_LOOP based on BMCR_LOOP is left in place though as it might provide useful for debugging). For most mii(4) drivers it was unclear whether the PHYs driven by them actually support loopback or not. Moreover, typically loopback mode also needs to be activated on the MAC, which none of the Ethernet drivers using mii(4) implements. Given that loopback media has no real use (and obviously hardly had a chance to actually work) besides for driver development (which just loopback mode should be sufficient for though, i.e one doesn't necessary need support for loopback media) support for it is just dropped as both NetBSD and OpenBSD already did quite some time ago. - Let mii_phy_add_media() also announce the support of IFM_NONE. - Restructure the PHY entry points to use a structure of entry points instead of discrete function pointers, and extend this to include a "reset" entry point. Make sure any PHY-specific reset routine is always used, and provide one for lxtphy(4) which disables MII interrupts (as is done for a few other PHYs we have drivers for). This includes changing NIC drivers which previously just called the generic mii_phy_reset() to now actually call the PHY-specific reset routine, which might be crucial in some cases. While at it, the redundant checks in these NIC drivers for mii->mii_instance not being zero before calling the reset routines were removed because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. Consequently, NIC drivers now no longer should call mii_phy_reset() directly, so it was removed from EXPORT_SYMS. - Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe(). The purpose of that function is to perform the common steps to attach a PHY driver instance and to hook it up to the miibus(4) instance and to optionally also handle the probing, addition and initialization of the supported media. So all a PHY driver without any special requirements has to do in its bus attach method is to call mii_phy_dev_attach() along with PHY-specific MIIF_* flags, a pointer to its PHY functions and the add_media set to one. All PHY drivers were updated to take advantage of mii_phy_dev_attach() as appropriate. Along with these changes the capability mask was added to the mii_softc structure so PHY drivers taking advantage of mii_phy_dev_attach() but still handling media on their own do not need to fiddle with the MII attach arguments anyway. - Keep track of the PHY offset in the mii_softc structure. This is done for compatibility with NetBSD/OpenBSD. - Keep track of the PHY's OUI, model and revision in the mii_softc structure. Several PHY drivers require this information also after attaching and previously had to wrap their own softc around mii_softc. NetBSD/OpenBSD also keep track of the model and revision on their mii_softc structure. All PHY drivers were updated to take advantage as appropriate. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - According to IEEE 802.3-2002 the bits actually have to be reversed when mapping an OUI to the MII ID registers. All PHY drivers and miidevs where changed as necessary. Actually this now again allows to largely share miidevs with NetBSD, which fixed this problem already 9 years ago. Consequently miidevs was synced as far as possible. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.

if_arge has had a strange bug that only appears during high traffic levels. TX would hang, RX wouldn't. A bit of digging showed the interface send queue was full, but IFF_DRV_OACTIVE was clear and the hardware TX queue was empty.
It turns out that there wasn't a check to drain the interface send queue once hardware TX had completed, so if the interface send queue had filled up in the meantime, subsequent packets would be dropped by the higher layers and if_start (and thus arge_start()) would never be called.
The fix is simple - call arge_start_locked() in the software interrupt handler after the hardware TX queue has been handled or a TX underrun occured. This way the interface send queue gets drained.

A handful of the openwrt devices use a MAC address that's at a hard-coded offset in the flash.
Some devices (eg the TPLink WR-1043ND) don't have a flash environment partition which can be queried for the current board settings.
This particular workaround allows for image creators to use a hint to set the base MAC address. For example:
hint.arge.0.eeprommac=0x1f01fc00
