[PATCH] net: bonding: Fix transmit load balancing in balance-alb mode
From: Kosuke Tatsukawa
Date: Thu Jul 20 2017 - 01:33:17 EST
balance-alb mode used to have transmit dynamic load balancing feature
enabled by default. However, transmit dynamic load balancing no longer
works in balance-alb after commit 8b426dc54cf4 ("bonding: remove
hardcoded value").
Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to
send packets. This function uses the parameter tlb_dynamic_lb.
tlb_dynamic_lb used to have the default value of 1 for balance-alb, but
now the value is set to 0 except in balance-tlb.
Re-enable transmit dyanmic load balancing by initializing tlb_dynamic_lb
for balance-alb similar to balance-tlb.
