networkd: add support for bond transmit hash policy
This patch adds support the transmit hash policy to use for slave selection in balance-xor, 802.3ad, and tlb modes layer2, layer3+4, layer2+3, encap3+4, encap3+4 Added: 1. BondXmitHashPolicy 2. conf param TransmitHashPolicy Test conf: [NetDev] Name=bond1 Kind=bond [Bond] Mode=802.3ad TransmitHashPolicy=layer2+3 test output: 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: slow Min links: 0 Aggregator selection policy (ad_select): stable bond bond1 has no active aggregator [tomegun: dropped bond_ prefix from new Bond variable, drop repeated man-page section]
