[PATCH 0/7] iptraf-ng: packet_get optimizations
by Vitezslav Samel
Main idea for this work is to minimize the work needed to be done
in packet_get(), which is the hottest path in the program.
Cheers,
Vita
Vitezslav Samel (7):
refactor struct pkt_hdr initialization
refactor pkt_cleanup()
packet_get(): optimize - move struct iovec
packet_get(): optimize - move struct sockaddr_ll
packet_get(): optimize - move struct msghdr
packet_get(): optimize - remove cache variables
pkt_hdr: make pkt_buf allocated from heap
