[src/trunk]: src/sys/dev - Call wm_kmrn_lock_loss_workaround_ich8lan() before...
details: https://anonhg.NetBSD.org/src/rev/86b1ae21976b
branches: trunk
changeset: 825406:86b1ae21976b

description:
- Call wm_kmrn_lock_loss_workaround_ich8lan() before any PHY access in
wm_linkintr_gmii().
- Register access in wm_kmrn_lock_loss_workaround_ich8lan() now works
correctly. Enable this function.
- Configure the LCD with the extended configuration region in NVM if it's
required.
- Add debug printf.
