There are a lot of TF_ flags.  Ususally we dont put an U to hex
flags.  The only one that is used for shifting is TF_TMR_REXMT after
going through the TF_TIMER define.  So I thought the cast there is
most specific.

Alternatives are:
- put U to every TF_ TCP flag
- put U to all TF_TMR_ timer flags
- put U to TF_TMR_REXMT retransmit timer flag
- cast TF_TIMER to unsigned (what I did)
- cast to unsigned in the TCP_TIMER_ARM, TCP_TIMER_ARM_MSEC,
  TCP_TIMER_DISARM, TCP_TIMER_ISARMED macros where the shift happens.

There is no best, minimalistic and most consistent solution.
