This looks good.  I made a list of drivers that can possibily use this helper.

Finding symbol: PTP_CLASS_PMASK

*** drivers/net/dsa/mv88e6xxx/hwtstamp.c:
parse_ptp_header[223]          switch (type & PTP_CLASS_PMASK) {

*** drivers/net/ethernet/mellanox/mlxsw/spectrum_ptp.c:
mlxsw_sp_ptp_parse[335]        switch (ptp_class & PTP_CLASS_PMASK) {

*** drivers/net/ethernet/ti/am65-cpts.c:
am65_skb_get_mtype_seqid[761]  switch (ptp_class & PTP_CLASS_PMASK) {

*** drivers/net/ethernet/ti/cpts.c:
cpts_skb_get_mtype_seqid[459]  switch (ptp_class & PTP_CLASS_PMASK) {

*** drivers/net/phy/dp83640.c:
match[815]                     switch (type & PTP_CLASS_PMASK) {
is_sync[990]                   switch (type & PTP_CLASS_PMASK) {

*** drivers/ptp/ptp_ines.c:
ines_match[457]                switch (ptp_class & PTP_CLASS_PMASK) {
is_sync_pdelay_resp[703]       switch (type & PTP_CLASS_PMASK) {

I'll test the marvell switch with your change and let you know...

Thanks,
