Merging TranslateReturnCode into wolfSSL_LastError dropped the IP_SOCK_getsockopt(SO_ERROR) lookup emNET integrations need to retrieve the canonical IP_ERR_* for a failed recv/send, leaving a broken branch that returned the raw value and mishandled the POSIX-facade convention. Restore the historic lookup (fixing the optlen pointer-vs-int typo along the way) and add a CI test that builds wolfSSL with -DWOLFSSL_EMNET against a clean-room shim providing an emNET-faithful IP_SOCK_getsockopt (SO_ERROR-then-errno fallback, since Linux does not stash EAGAIN in SO_ERROR); recv/send fall through to glibc.

/* IP.h -- clean-room shim for the subset of SEGGER emNET (embOS/IP) API
|
|
* that wolfSSL's WOLFSSL_EMNET port compiles against. Written from the
|
|
* public API surface documented in SEGGER UM07001; contains no SEGGER
|
|
* source.
|
|
*
|
|
* Scope: enough to build wolfSSL with -DWOLFSSL_EMNET on a POSIX host
|
|
* for CI test purposes. Only error constants and IP_SOCK_getsockopt
|
|
* are provided here; send/recv fall through to glibc's POSIX
|
|
* implementation, and the canonical IP_ERR_* lookup is emulated by
|
|
* IP_SOCK_getsockopt in emnet_shim.c.
