Subject: [PATCH 6/6] net: dsa: mv88e6xxx: enable support for 88E6361 switch

Marvell 88E6361 is an 8-port switch derived from the
|
|
88E6393X/88E9193X/88E6191X switches family. It can benefit from the
|
|
existing mv88e6xxx driver by simply adding the proper switch description in
|
|
the driver. Main differences with other switches from this
|
|
family are:
|
|
- 8 ports exposed (instead of 11): ports 1, 2 and 8 not available
|
|
- No 5GBase-x nor SFI/USXGMII support
