If anyone has any objections, please let me know. ------------------ From: Jiri Pirko [ Upstream commit a652208e0b52c190e57f2a075ffb5e897fe31c3b ] Check (ha->addr == dev->dev_addr) is always true because dev_addr_init() sets this. Correct the check to behave properly on addr removal. Signed-off-by: Jiri Pirko Signed-off-by: David S.
