As long as TCP_TMR_INTERVAL is #defined to the interval by which you actually call the timer function, any value should be fine. Anything below 250 or so should be fine. But you will probably mainly just waste CPU cycles if you call it very often, like every 1ms.

Should it be set to 250? I've seen some places (this forum for instance) where people seem to have set it to 100.

Not sure, I'd have to look at the code and specifications to be able to
say what were acceptable values.  There is some flexibility in the
value, and 100 may be OK.
