Subject: dsa: add support for the Marvell 88E6095/6095F switch chips
X-Git-Tag: v2.6.30-rc1~662^2~146
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=076d3e10a54caa2c148de5732c126c7a31381d48
dsa: add support for the Marvell 88E6095/6095F switch chips
Add support for the Marvell 88E6095/6095F switch chips. These
chips are similar to the 88e6131, so we can add the support to
mv88e6131.c easily.
Thanks to Gary Thomas <gary@mlbassoc.com> and Jesper Dangaard
Brouer <hawk@diku.dk> for testing various patches.
