X-Git-Tag: 2.1b_release~9342^2~208 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=801e9096c566d40d2e7c9903dc902fa01a5a0b36;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git qlge: Fix bonding mac address bug. Use local copy of current mac address when initializing. In bonding testing we saw cases where dev_addr was out of data causing failover errors. Signed-off-by: Ron Mercer Signed-off-by: David S.
