bonding: Allow userspace to set actors' system_priority in AD system
This patch allows user to randomize the system-priority in an ad-system. The allowed range is 1 - 0xFFFF while default value is 0xFFFF. If user does not specify this value, the system defaults to 0xFFFF, which is what it was before this patch. Following example code could set the value - # modprobe bonding mode=4 # sys_prio=$(( 1 + RANDOM + RANDOM )) # echo $sys_prio > /sys/class/net/bond0/bonding/ad_actor_sys_prio # echo +eth1 > /sys/class/net/bond0/bonding/slaves ... # ip link set bond0 up Signed-off-by: Mahesh Bandewar <maheshb@google.com> Reviewed-by: Nikolay Aleksandrov <nikolay@redhat.com> [jt: * fixed up style issues reported by checkpatch * changed how the default value is set in bond_check_params(), this makes the default consistent between what gets set for a new bond and what the default is claimed to be in the bonding options.] Signed-off-by: Jonathan Toppins <jtoppins@cumulusnetworks.com> Signed-off-by: David S.
