net: dsa: bcm_sf2: Fix number of CFP entries for BCM7278

2017-09-20T06:22:08+00:00

[ Upstream commit df191632f814357ee4d646421662d866028b569d ] BCM7278 has only 128 entries while BCM7445 has the full 256 entries set, fix that.

net: dsa: b53: Add missing ARL entries for BCM53125

2017-08-11T15:33:56+00:00

[ Upstream commit be35e8c516c1915a3035d266a2015b41f73ba3f9 ] The BCM53125 entry was missing an arl_entries member which would basically prevent the ARL search from terminating properly. This switch has 4 ARL entries, so add that.

net: dsa: mv88e6xxx: Enable CMODE config support for 6390X

2017-08-11T15:33:56+00:00

[ Upstream commit bb0a2675f72b458e64f47071e8aabdb225a6af4d ] Commit f39908d3b1c45 ('net: dsa: mv88e6xxx: Set the CMODE for mv88e6390 ports 9 & 10') added support for setting the CMODE for the 6390X family, but only enabled it for 9290 and 6390 - and left out 6390X. Fix support for setting the CMODE on 6390X also by assigning mv88e6390x_port_set_cmode() to the .port_set_cmode function pointer in mv88e6390x_ops too.

net: dsa: mv88e6xxx: add VTU support for 88E6390

2017-05-01T19:03:13+00:00

The 6390 family of chips use only 2 of the 3 VTU Data registers to pack the MemberTag and PortState VLAN data. This means that they must be written or read before or after each VTU/STU operations. Implement this variant to add support for VTU with such chips. These chips have a 13th bit for the VID thus set their max_vid to 8191.

net: dsa: mv88e6xxx: support the VTU Page bit

2017-05-01T19:03:13+00:00

Newer chips such as the 88E6390 have a VTU Page bit in the VTU VID register to specify a 13th bit for the VID. This can be used to support 8K VLANs. When dumping the whole VTU, all VID bits must be set to one, including this VTU Page bit. Add support for VID greater than 4095. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller
