New Revision: 233991
URL: http://svn.freebsd.org/changeset/base/233991
Log:
- Do not reinitialize the card if it is already running.
This fixes bootp on if_smc, as bootp code perform SIOCSIFADDR
ioctl call immediately after sending the request (which causes
if_init being called) which causes the adapter to drop all the
packets received in the meantime.
