Subject: [PATCH v2 0/8] use true mac address of LAN local remote hosts
Date: Thu, 12 Jun 2025 00:21:44 -0400	[thread overview]
Message-ID: <20250612042152.695879-1-jmaloy@redhat.com> (raw)

Bug #120 asks us to use the true MAC addresses of LAN local
remote hosts, since some programs need this information.
These commits introduces this for ARP, NDP, UDP, TCP and
ICMP.

Jon Maloy (8):
  netlink: Add function to extract mac addresses from arp table
  arp: respond with true mac address of LAN local remote hosts
  flow: add mac address of LAN local remote hosts to flow
  udp: forward external source mac address through tap interface
  tcp: forward external source mac address through tap interface
  tap: change signature of function tap_push_l2h()
  tcp: make tcp_rst_no_conn() respond with correct mac address
  icmp: let icmp use mac address from flowside structure
