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.
