bonding: Implement user key part of port_key in an AD system.
The port key has three components - user-key, speed-part, and duplex-part. The LSBit is for the duplex-part, next 5 bits are for the speed while the remaining 10 bits are the user defined key bits. Get these 10 bits from the user-space (through the SysFs interface) and use it to form the admin port-key. Allowed range for the user-key is 0 - 1023 (10 bits). If it is not provided then use zero for the user-key-bits (default). It can set using following example code - # modprobe bonding mode=4 # usr_port_key=$(( RANDOM & 0x3FF )) # echo $usr_port_key > /sys/class/net/bond0/bonding/ad_user_port_key # 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 * fixed up context from change in ad_actor_sys_prio patch] Signed-off-by: Jonathan Toppins <jtoppins@cumulusnetworks.com> Signed-off-by: David S.
