From 6929fe8a37365148228206eea8577b3524afc463 Mon Sep 17 00:00:00 2001 From: Ronghua Zang Date: Thu, 15 Jul 2010 22:18:47 -0700 Subject: net-next: vmxnet3 fixes [2/5] Interrupt control bitmap A new bit map 'intrCtrl' is introduced in the DriverShared area. The driver should update VMXNET3_IC_DISABLE_ALL bit before writing IMR. Signed-off-by: Ronghua Zang Signed-off-by: Shreyas Bhatewara Signed-off-by: David S.
