New Revision: 357010
URL: https://svnweb.freebsd.org/changeset/base/357010
Log:
Introduce flag IFF_NEEDSEPOCH that marks Ethernet interfaces that
supposedly may call into ether_input() without network epoch.
They all need to be reviewed before 13.0-RELEASE. Some may need
be fixed. The flag is not planned to be used in the kernel for
a long time.
