bonding: do not set slave_dev npinfo before slave_enable_netpoll in bond_enslave
After Commit 8a8efa22 ("bonding: sync netpoll code with bridge"), it would set slave_dev npinfo in slave_enable_netpoll when enslaving a dev if bond->dev->npinfo was set. However now slave_dev npinfo is set with bond->dev->npinfo before calling slave_enable_netpoll. With slave_dev npinfo set, __netpoll_setup called in slave_enable_netpoll will not call slave dev's .ndo_netpoll_setup(). It causes that the lower dev of this slave dev can't set its npinfo. One way to reproduce it: # modprobe bonding # brctl addbr br0 # brctl addif br0 eth1 # ifconfig bond0 192.168.122.1/24 up # ifenslave bond0 eth2 # systemctl restart netconsole # ifenslave bond0 br0 # ifconfig eth2 down # systemctl restart netconsole The netpoll won't really work. This patch is to remove that slave_dev npinfo setting in bond_enslave(). Fixes: 8a8efa22 ("bonding: sync netpoll code with bridge") Signed-off-by:Xin Long <lucien.xin@gmail.com> Signed-off-by:
