[lwip-users] lwIP Checksum routine

Hi all,
The lwip_chksum() function in lwip/src/core/inet.c seems to be unoptimized. This is doing halfword reads and additions. Wouldnt it be better to do word accesses and hence additions? There would be some prologue and epilogue code to checks for bringing the buffer to halfword->word boundaries. HAs anyone tried doing the same for any of their ports? Or am I missing something out here?
