This is intended to help in diagnostics and debugging of NIC and stack flowid support. Eventually this will grow another column (RSS CPU ID) but that currently isn't cached in the inpcb. There's also no clean flowtype -> flowtype identifier string. This is the mbuf M_HASHTYPE_* values for RSS. Here's some example output: adrian@adrian-hackbox:~/work/freebsd/head/src % netstat -Rn | more Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address flowid ftype tcp4 0 0 10.11.1.65.22 10.11.1.64.12409 29041942 2 udp4 0 0 127.0.0.1.123 *.* 00000000 0 udp6 0 0 fe80::1%lo0.123 *.* 00000000 0 udp6 0 0 ::1.123 *.* 00000000 0 udp4 0 0 10.11.1.65.123 *.* 00000000 0 Tested: * amd64 system w/ igb NIC; local driver changes to expose RSS flowid in if_igb.
