From 237fbe0a1c4d0d97f2041006884e42d4d704b906 Mon Sep 17 00:00:00 2001 From: Lawrence Stewart Date: Mon, 13 Jul 2009 11:51:02 +0000 Subject: Replace struct tcpopt with a proxy toeopt struct in the TOE driver interface to the TCP syncache. This returns struct tcpopt to being private within the TCP implementation, thus allowing it to be modified without ABI concerns. The patch breaks the ABI. Bump __FreeBSD_version to 800103 accordingly. The cxgb driver is the only TOE consumer affected by this change, and needs to be recompiled along with the kernel.
