T72: Fix compilations warnings for unaligned variable access
2022-10-22T72: Fix compilations warnings for unaligned variable accessVolodymyr Huti
- IPoE/DHCP4: Specify minimal suitable alignment explicitly. We need to guarantee 2 byte alignment for the `hdr` pointer in `ip_csum(uint16_t *buf)` calculation - PPPOE: Suppress false-positive warning for `sockaddr_pppox`. Similiar issue: https://github.com/kernelslacker/trinity/pull/40 - Introduce tmp variables to avoid alignment issues for SSTP/DHCPv6 For additional details: https://phabricator.accel-ppp.org/T72 Signed-off-by: Volodymyr Huti <v.huti@vyos.io>

2017-12-27ipoe: implemented new load balancing mechanismDmitry Kozlov
new config options: [ipoe] weight=N - global weight interface=ethX,weight=N - per-interface weight How it works: On reception of DHCPDISCOVER accel-ppp sends broadcast DHCP message to port 67 with same xid and add special vendor-specific option where encodes its current session count multipled by weight. On reception of such message accel-ppp searches session with same xid and compares weight. If received weight is less than session's weight then it terminates this session. per-interface weight=0 has special meaning as backup (fail-over) interface, f.e. it terminates session on any received weight. By default weight based load balancing is disabled. To enable need to specify global or/and per-interface weight.
