From 4b0d29dcfca9eafbf6e940862ab022df3ef2dd6f Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 29 Nov 2009 03:42:18 +0000 Subject: sfc: Turn pause frame generation on and off at the MAC, not the RX FIFO Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable bit in each MAC. RX_XOFF_MAC_EN bit always reads back as 0 so we need to set it correctly every time we modify RX_CFG_REG. Simplify this by always setting it to 1 and only changing the enable bits in the MACs.
