igb: Make Tx budget for NAPI user adjustable

Browse source

This change is to make the NAPI budget limits for transmit
adjustable.  Currently they are only set to 128, and when
the changes/improvements to NAPI occur to allow for adjustability,
it would be possible to tune the value for optimal
performance with applications such as routing.

v2: remove tie between NAPI and interrupt moderation
    fix work limit define name (s/IXGBE/IGB/)
    Update patch description to better reflect patch
