- On ICH8, call wm_gig_downshift_workaround_ich8lan() when link changed down.
- Drop PHY_CTRL_GBE_DIS explicitly in wm_lplu_d0_disable() in case BIOS sets this bit. - Fix two bugs in wm_kmrn_lock_loss_workaround_ich8lan(). Now the function checks the status correctly but it causes linkdown up to 10 times, so it's disabled for the time being.
