TCP Statistics

Four new counters are added to the tcp_statistics structure. The output of this structure can be viewed from the /proc filesystem. Network statistic programs such as netstat use this information to display statistics to the user.

The new counters added are as follows:

TcpTaoOk:

counts the number of TAO tests that passed

TcpTaoFail:

counts the number of TAO tests that failed

TcpBadCCecho:

counts the number of invalid CCecho options received

TcpCCdrop:

counts the number of invalid CC options received
