Gregory Nutt 75cc19ebb4 net/tcp: Fix a deadlock condition that can occur when (1) all network logic runs on a single work queue, (1) TCP write buffering is enabled, and (2) we run out of IOBs. In this case, the TCP write buffering logic was blocking on iob_alloc() with the network locked. Since the network was locked, the device driver polls that would provide take the write buffer data and release the IOBs could not execute. This fixes the problem by unlocking the network lock while waiting for the IOBs.

This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
