[edk2-devel] [PATCH edk2-platforms v4 0/9] BCM genet fixes

[Ard Biesheuvel]

This fixes the multicast/broadcast/promisc handling, and switches to
ordinary page allocations for RX buffers. Patch #1 is cosmetic only.

Note that these apply on top of the series sent out by Samer, and is
intended to be squashed into that series before merging.

Changes since v3:
- more cosmetic tweaks in #1
- move DmaUnmap() for TX buffers to the correct place
- use MemoryFence() instead of DSB for MMIO write ordering
- add unload support to the driver
- remove the Ax88772b driver from the RPi4 build - it is no longer needed,
  and misbehaves when no cable is connected.

Changes since v2:
- fix MDF filter handling (fixes issue reported by Samer)
- add patch to deal with ExitBootServices() so we don't leave the RX DMA
  ring running when we enter the OS
