* update to lwIP-2.1.0rc1: partial SACK support fix #4176 * hash fix * get some flash back due to mistake in conf (fragmentation & reassembly was incorrectly enabled) (ahah I scared you) * add missing include files * update to lwip-2.1.0(release) + remove unused lwIP's include files * lwIP release 2.1.0, SACK is now default, bigger, no-SACK is selectable * fix ldscript * pio * rename 'sack' option to 'feat'ure option, + IP fragmentation/reassembly * merge, fix pio * change internal/hidden string * pio: more lwip2 configuration: + without sack for no change in flash footprint
