Subject: [PATCH net 0/2] net: enetc: add more checks to enetc_set_rxfh()
Date: Wed, 25 Mar 2026 14:56:45 +0800 [thread overview]
Message-ID: <20260325065647.2882997-1-wei.fang@nxp.com> (raw)
ENETC only supports Toeplitz algorithm, and VFs do not support setting
the RSS key, but enetc_set_rxfh() does not check these constraints and
silently accepts unsupported configurations. This may mislead users or
tools into believing that the requested RSS settings have been
successfully applied. So add checks to reject unsupported hash functions
and RSS key updates on VFs, and return "-EOPNOTSUPP" to user space.
Wei Fang (2):
net: enetc: check whether the RSS algorithm is Toeplitz
net: enetc: do not allow VF to configure the RSS key
