[PATCH] ip_conntrack_proto_tcp

Hi there,

Attached patch for ip_conntrack to account TCP sessions started with SYN
+PUSH flags. Looks weird, but some HW vendors do TCP their own way. 

Let's earn some points from RFC 1025.

Cheers,
Vlad.

[NETFILTER] ip_conntrack SYN PUSH patch
	
Some Qlogic iSCSI HBA hardware like QLA4010 up to firmware 3.0.0.4
initiates TCP with SYN and PUSH flags set.
Linux TCP/IP stack works fine with that.
Make ip_conntrack do the same.
