Fabio Estevam 235bde1ed3 net: fec: Call swap_buffer() prior to IP header alignment
Commit 3ac72b7b63 ("net: fec: align IP header in hardware") breaks
networking on mx28.

There is an erratum on mx28 (ENGR121613 - ENET big endian mode
not compatible with ARM little endian) that requires an additional
byte-swap operation to workaround this problem.

So call swap_buffer() prior to performing the IP header alignment
to restore network functionality on mx28.
