[PATCH net 1/7] be2net: Fix to prevent Tx stall on SH-R when packet size < 32

[Ajit Khaparde <ajit.khaparde@emulex.com>]

Tx on SH-R can lockup if the packet size is less than 32 bytes.
Pad such packets to a safer 36-byte size.
Patch uses the Lancer-R workaround - which checks for packet <= 32-bytes
