[lwip-devel] [bug #52836] altcp_write error because of invalid sndbuf available returned

[David GIRAULT]

Follow-up Comment #5, bug #52836 (project lwip):

Hi Simon,

FYI, just found the following function in mbedTLS that will return the exact
value required for the ssl_added variable.

int mbedtls_ssl_get_record_expansion( const mbedtls_ssl_context *ssl )

It take care of the negociated cipher suite, and record header size.

So I think it may be used instead of the obvious calculation I use in may
orignial patch.
