H A D | dpaa_ethtool.c | diff 5d93cfcf Mon Oct 17 14:22:38 MDT 2022 Sean Anderson <sean.anderson@seco.com> net: dpaa: Convert to phylink This converts DPAA to phylink. All macs are converted. This should work with no device tree modifications (including those made in this series), except for QSGMII (as noted previously). The mEMAC configuration is one of the tricker areas. I have tried to capture all the restrictions across the various models. Most of the time, we assume that if the serdes supports a mode or the phy-interface-mode specifies it, then we support it. The only place we can't do this is (RG)MII, since there's no serdes. In that case, we rely on a (new) devicetree property. There are also several cases where half-duplex is broken. Unfortunately, only a single compatible is used for the MAC, so we have to use the board compatible instead. The 10GEC conversion is very straightforward, since it only supports XAUI. There is generally nothing to configure. The dTSEC conversion is broadly similar to mEMAC, but is simpler because we don't support configuring the SerDes (though this can be easily added) and we don't have multiple PCSs. From what I can tell, there's nothing different in the driver or documentation between SGMII and 1000BASE-X except for the advertising. Similarly, I couldn't find anything about 2500BASE-X. In both cases, I treat them like SGMII. These modes aren't used by any in-tree boards. Similarly, despite being mentioned in the driver, I couldn't find any documented SoCs which supported QSGMII. I have left it unimplemented for now. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Signed-off-by: David S.

It's about time the driver makes use of this h/w capability, by supporting fixed buffer sizes and Rx S/G. The buffer size given to eTSEC for reception is fixed to 1536B (must be multiple of 64), which is the same default buffer size as before, used to accommodate standard MTU (1500B) size frames. As before, eTSEC can receive frames of up to 9600B. Individual Rx buffers are mapped to page halves (page size for eTSEC systems is 4KB). The skb is built around the first buffer of a frame (using build_skb()). In case the frame spans multiple buffers, the trailing buffers are added as Rx fragments to the skb. The last buffer in frame is marked by the L status flag. A mechanism is in place to reuse the pages owned by the driver (for Rx) for subsequent receptions. Supporting fixed size buffers allows the implementation of Rx S/G, which in turn removes the memory pressure issues the driver had before when MTU was set for jumbo frame reception. Also, in most cases, the Rx path becomes faster due to Rx page reusal, since the overhead of allocating new rx buffers is removed from the fast path.

Instead of allocating a single new buffer (skb) on each iteration, bundle the allocation of several rx buffers at a time. This also opens the path for further memory optimizations. Remove useless check of rxq->rfbptr, since this patch touches rx pause frame handling code as well. rxq->rfbptr is always initialized as part of Rx BD ring init.

The current implementation treats PHY ID of zero as a non-error and valid PHY ID, and causing the PHY device failed to bind to the Marvell driver. For such devices, we do an additional probe in the Clause-45 space, if a valid PHY ID is returned, we then proceed to attach the PHY device to the matching PHY ID driver.

We want to use it as a bit array indicating which MMDs are present, but we also want to know if the Clause 22 registers are present. Since "devices in package" is a term used in the 802.3 specification, keep this as the as-specified values read from the PHY, and introduce a new member "mmds_present" to indicate which MMDs are actually present in the PHY, derived from the "devices in package" value.
