Johannes Stezenbach 2d576e2a22 udhcpc: make DHCP packets to have at least 300 DHCP bytes 
Commit b8b72f02 removed all padding from DHCP packets
to fix operation with buggy servers which can't handle
maximum sized packets.  But it introduced a regression
with buggy routers which drop DHCP packets smaller
than 300 bytes (i.e. 342 byte ethernet packets).
Add back some padding to work around.
