Subject: [PATCH v1] bridge: cfm: fix enum typo in br_cc_ccm_tx_parse
Date: Wed, 20 Dec 2023 15:59:14 +0800
Message-Id: <20231220075914.2426376-1-linma@zju.edu.cn>
Precedence: bulk

It appears that there is a typo in the code where the nlattr array is
being parsed with policy br_cfm_cc_ccm_tx_policy, but the instance is
being accessed via IFLA_BRIDGE_CFM_CC_RDI_INSTANCE, which is associated
with the policy br_cfm_cc_rdi_policy.

Though it seems like a harmless typo since these two enum owns the exact
same value (1 here), it is quite misleading hence fix it by using the
correct enum IFLA_BRIDGE_CFM_CC_CCM_TX_INSTANCE here.

Fixes: 2be665c3940d ("bridge: cfm: Netlink SET configuration Interface.")
