From e18ce3465477502108187c6c08b6423fb784a313 Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Tue, 16 Dec 2008 02:00:00 -0800 Subject: net: Move flow control definitions to mii.h flags used within drivers for indicating tx and rx flow control are defined in 4 drivers (and probably more), move these constants to mii.h. The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3. Signed-off-by: Steve Glendinning Signed-off-by: David S.
