sys/dev/fdt : if_fec.c
Log message:
Rework fec(4). I have written this driver in 2012 as my first ever
ethernet controller driver. Handling of descriptors and buffers has
not been great. There was no way to recover from a full tx queue.
This introduces a mechanism akin to dwxe(4) and tsec(4) and fixes
that. On rd we now map mbufs directly. On tx we can do that as
well for newer SoCs. The i.MX6 Q/DL generation still needs a bounce
buffer on tx for proper alignment.
Tested with bluhm on Cubox-i (armv7) and Hummingboard Pulse (arm64)
