Subject: DM9000: Fix endian-ness of data accesses.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=931165739a75f88530d5b02cafaacf9bb6b66d87;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

DM9000: Fix endian-ness of data accesses.

Patch from: Laurent Pinchart <laurentp@cse-semaphore.com>

This patch splits the receive status in 8bit wide fields and convert the
packet length from little endian to CPU byte order.
