[PATCH] ip_conntrack TCP: Accept SYN+PUSH like SYN
Some devices (e.g. Qlogic iSCSI HBA hardware like QLA4010 up to firmware
3.0.0.4) initiates TCP with SYN and PUSH flags set.
The Linux TCP/IP stack deals fine with that, but the connection tracking
code doesn't.
This patch alters TCP connection tracking to accept SYN+PUSH as a valid
flag combination.
