This driver does not use the old GPIO includes so drop
them.

net: dsa: microchip: fix unicast frame leak

2018-12-21T00:19:29+00:00

Port partitioning is done by enabling UNICAST_VLAN_BOUNDARY and changing
the default port membership of 0x7f to other values such that there is
no communication between ports.  In KSZ9477 the member for port 1 is
0x41; port 2, 0x42; port 3, 0x44; port 4, 0x48; port 5, 0x50; and port 7,
0x60.  Port 6 is the host port.

Setting a zero value can be used to stop port from receiving.

However, when UNICAST_VLAN_BOUNDARY is disabled and the unicast addresses
are already learned in the dynamic MAC table, setting zero still allows
devices connected to those ports to communicate.  This does not apply to
multicast and broadcast addresses though.  To prevent these leaks and
make the function of port membership consistent UNICAST_VLAN_BOUNDARY
should never be disabled.

Note that UNICAST_VLAN_BOUNDARY is enabled by default in KSZ9477.

net: dsa: ksz: Add reset GPIO handling

2018-12-10T20:07:56+00:00

Add code to handle optional reset GPIO in the KSZ switch driver. The switch
has a reset GPIO line which can be controlled by the CPU, so make sure it is
configured correctly in such setups.

Break KSZ9477 DSA driver into two files in preparation to add more KSZ
switch drivers.
Add common functions in ksz_common.h so that other KSZ switch drivers
can access code in ksz_common.c.
Add ksz_spi.h for common functions used by KSZ switch SPI drivers.
