According to release notes it seems that we can also differentiate
88E211X from 88E218X (via bit 3 in register 1.3):
88E211X has 0x09B9
88E218X has 0x09B1
but not 88E2110 from 88E2111
nor 88E2180 from 88E2181.
These can be differentiated via register
3.0004.7
(bit 7 of MDIO_MMD_PCS.MDIO_SPEED., which says whether device is capable
of 5g speed)
I propose creating separate structures for mv88x3340 and mv88e218x.
We can then print the remaining info as
"(not) macsec/ptp capable"
or
"(not) 5g capable"
What do you think?
