Subject: [PATCH] ibm_newemac: Fix EMACx_TRTR[TRT] bit shifts
Date: Tue, 17 Nov 2009 18:56:55 -0600 [thread overview]
Message-ID: <1258505815-31261-1-git-send-email-dmitchell@appliedmicro.com> (raw)
The TRT bit shifts were reversed for EMAC4 and non-EMAC4 during the
port from ibm_emac to ibm_newemac. This patch corrects that error.

For those curious, these bits control the TX threshold.
