Interesting. The original commit says:
SERDESes can do USXGMII, 10GBASER and 5GBASER (on 6191X only one
SERDES is capable of more than 1g; USXGMII is not yet supported
with this change)
which is ambiguously worded - so I guess we now know that it's only
port 10 that supports speeds above 1G.
Can ports 0 / 1 / 10 be changed at runtime (iow, is the C_Mode field
writable on these ports?)
Thanks.
