Follow-up Comment #6, bug #34176 (project lwip):
The comment above TCP_SNDLOWAT says it must be less than TCP_SND_BUF.
but, TCP_SND_BUF is by default defined to (2 * TCP_MSS)
and then
TCP_SNDLOWAT = MAX(TCP_SND_BUF / 2, 2 * TCP_MSS + 1) = MAX(TCP_SND_BUF / 2,
TCP_SND_BUF + 1) = TCP_SND_BUF + 1
to sum it up,
1. the MAX() macro is irrelevant, and TCP_SNDLOWAT equals TCP_SND_BUF + 1
2. its always bigger than TCP_SND_BUF.
