These chips support standard Ethernet link modes as well, however, the circuitry is mutually exclusive and cannot be auto-detected. The link modes in question are 100Base-T1 as defined in IEEE802.3bw, based on Broadcom's 1BR-100 link mode, and newly defined 10Base-T1BRR (1BR-10 in Broadcom documents). Add optional brr-mode flag to switch the PHY to BroadR-Reach mode.
