Andrew Webster e221777a7a TCP: post buffer semaphore before re-acquiring both ...

TCP uses two semaphores for buffers, one for the entire buffer pool,
and one for the number of allowed buffers for readahead.  To avoid
double taking a semaphore under heavy load, release the semaphore
after waiting before trying to acquire both again.

iob_add_queue.c

Networking: The are issues with the TCP write-ahead buffering if CONFIG_NET_NOINTS is enabled: There is a possibility of deadlocks in certain timing conditions. I have not seen this with the Tiva driver that I have been users but other people claim to see the issue on other platforms. Certainly it is a logic error: The network should never wait for TCP read-ahead buffering space to be available. It should drop the packets immediately.
