[6]
Overrides the auto-negotiation master channel
that you set with the Auto-Negotiation Master
parameter, setting the new master channel
according to the value in register 0xCC[3:0].
While 0x0C0[6] has the value of 1, the channel
encoded in 0xCC[3:0] is the master channel.
While 0xC0[6] has the value of 0, the master
channel is the channel that you set with the
Auto-Negotiation Master parameter.

FEC_F[1:0]
[26:25
]
Received FEC ability bits. Bit [26] is FEC
requested and bit [25] is FEC ability. FEC
(F0:F1) is encoded in bits D46:D47 of the base
Link Codeword in Clause 73 AN. F0 is FEC
ability and F1 is FEC requested. Refer to Clause
73.6.5 of IEEE Std 802.3ap-2007.
