sys/dev/mii miidevs rlphy.c
sys/pci if_rl.c
Log:
Teach the rlphy driver how to do parallel link detection. If the link partner
doesn't support NWAY, the RealTek PHY (both the integrated ones on 8139
chips and the RTL8201L 10/100 PHY) will not report the link speed via
the ANLPAR or BMSR registers. For the 8201L, we need to look in magic
vendor-specific PHY register 0x19. For the 8139 MAC+PHY combo, we have
to be able to test the RL_MEDIASTAT register.
The changes to rlphy.c are based largely on the patch from PR 30836,
however I tried to eliminate some magic numbers by creating an entry
for the 8201 PHY in miidevs.
Also updated if_rl.c to allow the rlphy driver to read the RL_MEDIASTAT
register via the rl_miibus_readreg() routine.
