Consider collapsing writing related attrs in a nest into a single
if statement:

        if (nla_put_u32(skb, IFLA_BRIDGE_CFM_CC_CCM_TX_SEQ_NO_UPDATE,
                        mep->cc_ccm_tx_info.seq_no_update) ||
            nla_put_u32(skb, IFLA_BRIDGE_CFM_CC_CCM_TX_PERIOD,
                        mep->cc_ccm_tx_info.period) ||
                ...
