mongoose.c:24184:mg_tcpip_driv No free descriptors in MG_VERSION "7.19" latest commits

[Juggler-5]

Hello. I used MG_VERSION "7.19" from the near to it`s release date, and today I updated it to last commit (Merge pull request #3307 from cesanta/openssl). I use stm32f42(3)9 nucleo. After update I get errors like: "mongoose.c:24184:mg_tcpip_driv No free descriptors", and when I roll back to earlier 7.19 it all backs to normal.
Just letting you know. If you aware about the reasons already, please let me know as well.

Finally I got it, and eventhough nobody asks my opinion here, I'd like to express myself as humble as possible :)
Instead of
#ifndef MG_ETH_RAM
..
#define MG_ETH_RAM attribute((section(".eth_ram")))
..
#endif
that would be more user friendly to surprise the audience with focus like:
#if !defined MG_ETH_RAM
#error "Please provide RAM section for bla-bla-bla"
#endif
Seriously It is not funny at all to loose remote control of your device after upgrade with such a mute build rearrangement.
