Forgot to CC io_uring
Add support for per-queue rx buffer length configuration based on [2]
and basic infrastructure for using it in memory providers like
io_uring/zcrx. Note, it only includes net/ patches and leaves out
zcrx to be merged separately. Large rx buffers can be beneficial with
hw-gro enabled cards that can coalesce traffic, which reduces the
number of frags traversing the network stack and resuling in larger
contiguous chunks of data given to the userspace.
Same note as the last time, not great that it's over the 15 patches,
but I don't see a good way to shrink it considering that the original
series [2] is 22 patches long, and I'll somehow need to pull it it
into the io_uring tree after. Please let me know if there is a strong
feeling about that, and/or what would the preferred way be.
