Daniel P. Carvalho a8338c1add arch/mips/pic32mz: receive full size Ethernet frames. 
The RX byte count and the EMAC1MAXF limit both include the 4-byte FCS,
but the driver did not account for it:

- RXBUFSZ was programmed with CONFIG_NET_ETH_PKTSIZE, rounded down to
  16 bytes (1504 for 1514), so longer frames were split into fragments
  and dropped.
- EMAC1MAXF was set to CONFIG_NET_ETH_PKTSIZE, so the MAC rejected
  frames longer than CONFIG_NET_ETH_PKTSIZE - 4.
- d_len included the FCS.

Make room for the FCS in the buffers, program RXBUFSZ with the aligned
buffer size and EMAC1MAXF with CONFIG_NET_ETH_PKTSIZE + 4, and remove
the FCS from d_len.  The largest ping that got an answer was 1458
bytes; it is now 1472, the full 1500-byte MTU.
