Subject: fs_enet: fix freescale FCC ethernet dp buffer alignment
X-Git-Tag: v3.0-rc4~5^2~12
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cab758ef30e0e40f783627abc4b66d1b48fecd49;p=karo-tx-linux.git

fs_enet: fix freescale FCC ethernet dp buffer alignment

The RIPTR and TIPTR  (receive/transmit internal temporary data pointer),
used by microcode as a temporary buffer for data, must be 32-byte aligned
according to the RM for MPC8247.

Tested on mgcoge.
