Modified Files:
src/sys/dev/pci [netbsd-9]: if_wm.c if_wmreg.h
Log Message:
Pull up the following revisions, requested by msaitoh in ticket #1515:
sys/dev/pci/if_wm.c 1.741-1.749,
1.753-1.757,
1.762 via patch
sys/dev/pci/if_wmreg.h 1.126-1.127
- Fix I219 workaround in wm_flush_desc_rings().
- Add more statistics counters.
- To avoid releasing mutex temporally, use new
wm_set_mdio_slow_mode_hv_locked().
- No functional changes:
- Turn a locking botch (shouldn't drop lock on error) into a KASSERT
in wm_deferred_start_locked().
- Remove unneeded header inclusion.
- Use __BIT() a little.
- Modify comment and debug messages.
- Consistency use -1 instead of 1 for some error code.
- KNF.
