Subject: Check for the "break the loop" condition in the inner loop for TPACKET_V3.
X-Git-Tag: libpcap-1.8.1~13
X-Git-Url: https://git.tcpdump.org/libpcap/commitdiff_plain/abe6d6dd6ba3e0405dc78c50378d4f112456ef34

Check for the "break the loop" condition in the inner loop for TPACKET_V3.

Otherwise, if a callback calls pcap_breakloop(), the inner loop won't
terminate.
