+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.
