From 3c63dd5302a2f14c292a469b9934a8fc02b627cc Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Tue, 19 May 2015 10:01:19 -0700 Subject: [PATCH] Revert "e1000: fix sw fw sync on igb i210/i211" This reverts commit 17da7120249bfdef877f46be5bbcb3cc01212eb9. The i210/i211 do have the SW_FW_SYNC (0x5b5c) register and this is what should be used when acquiring the semaphore. I believe the issue that this patch was trying to resolve is now resolved by properly releasing the semaphore once no longer needed.
