From 15f5a585c6b8dac31ed0a55693aacf51934f0f5d Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 9 Aug 2005 20:17:28 -0700 Subject: [PATCH] [TG3]: Eliminate one register write in tg3_restart_ints() The register write to register 0x68 to restart interrupts is unnecessary as the interrupt wasn't masked in that register by the irq handler. This will save one register write in the fast path. Signed-off-by: Michael Chan Signed-off-by: David S.
