Subject: [PATCH net v2] net: ti: icssg-prueth: Fix r30 CMDs bitmasks
The bitmask for EMAC_PORT_DISABLE and EMAC_PORT_FORWARD has been changed
in the ICSSG firmware REL.PRU-ICSS-ETHERNET-SWITCH_02.02.12.05.
The current bitmasks are wrong and as a result EMAC_PORT_DISABLE and
EMAC_PORT_FORWARD commands doesn not work.
Update r30 commands to use the same bitmask as used by the ICSSG firmware
REL.PRU-ICSS-ETHERNET-SWITCH_02.02.12.05.
These bitmasks are not backwards compatible. This will work with
firmware version REL.PRU-ICSS-ETHERNET-SWITCH_02.02.12.05 and above but
not with lower firmware versions.
Fixes: e9b4ece7d74b ("net: ti: icssg-prueth: Add Firmware config and classification APIs.")
