[lwip-devel] [patch #6253] Added csum to struct pbuf.

[Simon Goldschmidt]

Follow-up Comment #12, patch #6253 (project lwip):

Andrey, I know this comment is a little late, I'm only starting to work on
this again now:

Why do you "calculate csum for it before I call udp_send (and do it fast in
asm)" instead of providing this fast asm routing as LWIP_CHKSUM macro?

Anyway, from your description, it seems to me as one checksum per packet
could also be sufficient...
