Convert alb_send_learning_packets and bond_has_this_ip to use the new netdev_walk_all_upper_dev_rcu API. In both cases this is just a code conversion; no functional change is intended. v2 - removed typecast of data and simplified bond_upper_dev_walk Signed-off-by: David Ahern <dsa@cumulusnetworks.com> --- drivers/net/bonding/bond_alb.c | 82 ++++++++++++++++++++++++++--------------- drivers/net/bonding/bond_main.c | 17 +++++---- 2 files changed, 61 insertions(+), 38 deletions(-)
