> Subject: [PATCH] igb: Fix a test with HWTSTAMP_TX_ON
> 
> 'HWTSTAMP_TX_ON' should be handled as a value, not as a bit mask.
> The modified code should behave the same, because HWTSTAMP_TX_ON is
> 1
> and no other possible values of 'tx_type' would match the test.
> However, this is more future-proof, should other values be allowed one day.
> 
> See 'struct hwtstamp_config' in 'include/uapi/linux/net_tstamp.h'
> 
> This fixes a warning reported by smatch:
>    igb_xmit_frame_ring() warn: bit shifter 'HWTSTAMP_TX_ON' used for
> logical '&'
> 
> Fixes: 26bd4e2db06be ("igb: protect TX timestamping from API misuse")
