New Revision: 254118
URL: http://svnweb.freebsd.org/changeset/base/254118
Log:
Fix for IPv4 fragment packets treated as RMCP.
bit25 of rxMode MAC register of 5762 needs to be set for rx mgmt
filter to work correctly when processing match for UDP header
fields. Otherwise false positive can occur which causes IPv4
fragment to be received by APE instead of host.
