* Teach the loopback interface about checksum generation and validationrwatson2009-03-151-11/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | avoidance: - Enable setting the RXCSUM and TXCSUM flags for loopback interfaces; set both by default. - When RXCSUM is set, flag packets sent over the loopback interface as having checked and valid IP, UDP, TCP checksums so that higher protocol layers won't check them. - Always clear CSUM_{IP,UDP_TCP} checksum required flags on transmit, as they will have gotten there as a result of TXCSUM being set. This is done only for packets explicitly sent over the loopback, not simulated loopback via if_simloop() due to !SIMPLEX interfaces, etc. Note that enabling TXCSUM but not RXCSUM will lead to unhappiness, as checksums won't be generated but will be validated. Kris reports that this leads to significant performance improvements in loopback benchmarking with TCP and UDP for throughput: RXCSUM RXCSUM+TXCSUM TCP 15% 37% UDP 10% 74% Update man page.
