|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix libpcap issue #893: check for invalid IPv4 addresses. This fixes errors such as: tcpdump -i lagg0 net 999.999.999.999 This was originally discovered on a Red Hat 7.7 server and verified to also be a bug on FreeBSD.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | run directly on netmap ports using netmap:foo or valeXX:YY device names. Modifications to existing code are small and trivial, the netmap-specific code is all in a new file. Please be aware that in netmap mode the physical interface is disconnected from the host stack, so libpcap will steal the traffic not just make a copy. For the full version of the code (including linux and autotools support) see https://code.google.com/p/netmap-libpcap/ MFC after: 3 days Notes: svn path=/head/; revision=272659

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The origin of WEP comes from IEEE Std 802.11-1997 where it defines whether the frame body of MAC frame has been encrypted using WEP algorithm or not. IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates whether the frame is protected by a cryptographic encapsulation algorithm.
