David Cermak 7b91343ca7 lwip: Fix ping socket create to allow for fd=0 ... 0 is a valid socket description, so should be accepted after we create a socket. In IDF, though, it's just a theoretical issue, as customers have to configure: * FD_SETSIZE = CONFIG_LWIP_MAX_SOCKETS (from makefiles) * CONFIG_VFS_SUPPORT_IO = n (from menuconfig) (this configuration is currently broken, but if we adjust the IDF here and there we could reproduce the issue)		2021-10-26 08:19:26 +02:00
