Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

MFC r304574-304575,304584: r304574: Correct DMA channel number selection on AR816x family of controllers. For Gigabit Ethernet version of AR816x, AR813x/AR815x except L1D controller, use vendor recommended ASPM parameters. While here, increase alc_dma_burst array size. Broken H/W can return bogus value in theory.
r304575: Add Killer E2400 Gigabit Ethernet support. It seems Killer E2200/E2400 has a BIOS misconfiguration or silicon bug which triggers DMA write errors when driver uses advertised maximum payload size. Force the maximum payload size to 128 bytes in DMA configuration. This change should fix occasional DMA write errors reported on Killer E2200.
r304584: Add a missing change in r304575.

Add support for QAC AR816x/AR817x Gigabit/Fast Ethernet controllers. These controllers seem to have the same feature of AR813x/AR815x and improved RSS support(4 TX queues and 8 RX queues). alc(4) supports all hardware features except RSS. I didn't implement RX checksum offloading for AR816x/AR817x just because I couldn't get confirmation from the Vendor whether AR816x/AR817x corrected its predecessor's RX checksum offloading bug on fragmented packets. This change adds supports for the following controllers. o AR8161 PCIe Gigabit Ethernet controller o AR8162 PCIe Fast Ethernet controller o AR8171 PCIe Gigabit Ethernet controller o AR8172 PCIe Fast Ethernet controller o Killer E2200 Gigabit Ethernet controller

Increase the number of TX DMA segments from 32 to 35. It turned out 32 is not enough to support a full sized TSO packet. While I'm here fix a long standing bug introduced in r169632 in bce(4) where it didn't include L2 header length of TSO packet in the maximum DMA segment size calculation.

Add a 'locked' variant of the foo_start() routine and call it directly from interrupt handlers and watchdog routines instead of queueing a task to call foo_start().

Add support for Atheros AR8151/AR8152 PCIe gigabit/fast ethernet controller. These controllers are known as L1D(AR8151) and L2CB/B2(AR8152). This change adds supports for the following controllers. o AR8151 v1.0(L1D) gigabit ethernet controller o AR8151 v2.0(L1D) gigabit ethernet controller o AR8152 v1.1(L2CB) fast ethernet controller o AR8152 v2.0(L2CB2) fast ethernet controller These controllers have the same feature of AR8131/AR8132 and support improved power saving control. The user visible change at this moment is reduced jumbo frame size from 9KB to 6KB. Many thanks to Atheros for continuing to support FreeBSD.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had.
