Subject: IB/ucm: Get rid of duplicate P_Key parameter
X-Git-Tag: v2.6.18-rc1~1110^2~9
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=75af9088514432ef0c1052ba3767ceb0beb6f101

IB/ucm: Get rid of duplicate P_Key parameter

The P_Key is provided into a SIDR REQ in two places, once as a
parameter, and again in the path record.  Remove the P_Key as a
parameter and always use the one given in the path record.

This change has no practical effect on ABI functionality.
