macb: Add support of the netpoll API (6e8cf5c0) · Commits · 戴 / test

With this patch in place, I'm successfully able to use the netconsole mechanism with the Calao USB-A9263 board, which uses the AT91SAM9263 CPU, which in terms of Ethernet controller is supported by the macb driver. Signed-off-by:
