networkd: bond add support for lacp rate
LacpduTransmitRate option specifies the rate in which link partner to transmit LACPDU packets in 802.3ad mode. Possible values slow : Request partner to transmit LACPDUs every 30 seconds fast : Request partner to transmit LACPDUs every 1 second The default is slow. chages: 1. Added enum bond_lacp_rate_table 2. gperf LacpduTransmitRate Test: conf file: [NetDev] Name=bond1 Kind=bond [Bond] Mode=802.3ad LacpduTransmitRate=fast test: cat /proc/net/bonding/bond1 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2+3 (2) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: fast Min links: 0 Aggregator selection policy (ad_select): stable bond bond1 has no active aggregator [tomegun: renamed from LacpduTransmitRate to LACPTransmitRate, manpage fixes and dropped bond_ prefix from variables]
