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. Requested by: gjb (re)

Add MSIX rewrite table quirk for use with VMs. This patch solves IRQ generation problems using the mlx5en(4) driver with xenserver v6.5.0 in SRIOV and PCI-passthrough modes. Until further the hw.pci.msix_rewrite_table quirk must be set manually in /boot/loader.conf . Reviewed by: jhb @ Sponsored by: Mellanox Technologies

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.
