Subject: Merge various urtwn(4) fixes from FreeBSD:
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a55d0e847635e195bea37dcd5f78aa205e5a834c;p=openbsd

Merge various urtwn(4) fixes from FreeBSD:
Match additional devices (RTL8188CU_3, DWA123D1, DWA125D1).
Fix efuse reading (fixes potential error in MAC address read from efuse).
Replace some magic numbers with macros.

Based on FreeBSD r270191, r273589, r281918, r281592, r282119, and r282623
