New Revision: 229057
URL: http://svn.freebsd.org/changeset/base/229057
Log:
MFC r226478:
Close a race where SIOCGIFMEDIA ioctl get inconsistent link status.
Because driver is accessing a common MII structure in
mii_pollstat(), updating user supplied structure should be done
before dropping a driver lock.
