Subject: [PATCH net 0/2] mlxsw: spectrum: Forward packets with an IPv4 link-local source IP
Date: Wed, 13 Aug 2025 13:47:07 +0200	[thread overview]
Message-ID: <cover.1755085477.git.petrm@nvidia.com> (raw)

By default, Spectrum devices do not forward IPv4 packets with a link-local
source IP (i.e., 169.254.0.0/16). This behavior does not align with the
kernel which does forward them. Fix the issue and add a selftest.

Ido Schimmel (2):
  mlxsw: spectrum: Forward packets with an IPv4 link-local source IP
  selftest: forwarding: router: Add a test case for IPv4 link-local
    source IP
