From 60948a415859cb859e24f0dfe739069d66577466 Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Sun, 6 Jan 2008 21:02:34 -0800 Subject: IB/ipath: Port config has on-chip effects for 7220 The number of configured ports for the 7220 changes the number of eager TIDs available per port, for all but port 0 (kernel port) which remains constant, so add a field to give port0 count separate from the portdata structure.
