Subject[PATCH net] net: dsa: bcm_sf2: Only 7278 supports 2Gb/sec IMP port
Date
The 7445 switch clocking profiles do not allow us to run the IMP port at
2Gb/sec in a way that it is reliable and consistent. Make sure that the
setting is only applied to the 7278 family.

Fixes: 8f1880cbe8d0 ("net: dsa: bcm_sf2: Configure IMP port for 2Gb/sec")
