I think you may have accidentally squashed the lwipopts.h and netstart.c
changes into this commit instead of 4/7.
Changes to imported code should follow the same rules as rtems-libbsd
for easier updating. It looks like you did this in most places, but a
few instances are called out below where you didn't.
More comments inline below.
