Gregory Nutt 427b3b8fcb Squashed commit of the following: 
net/utils:  return from net_breaklock() was being clobbered.
    net/:  Replace all calls to iob_alloc() with calls to net_ioballoc() which will release the network lock, if necessary.
    net/utils, tcp, include/net:  Separate out the special IOB allocation logic and place it in its own function.  Prototype is available in a public header file where it can also be used by network drivers.
    net/utils: net_timedwait() now uses new net_breaklock() and net_restorelock().

arp
net/: More fixes to wrong comments from old change from the interrupt driven network to the work-queue driven network.

devif
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.

ieee802154
Squashed commit of the following:
2018-07-07 08:26:13 -06:00
igmp
Standardization of some function headers.
2018-03-13 09:52:27 -06:00
inet
net/: Fix some incorrect comments that go back for years (but have also been cloned in newer files). The network was once interrupt driver, but now runs on the work queue with a semaphore to enforce mutual exclusion.

Trivial typo fixes

loopback
Fix IPv6 loopback driver that depended on the removed g_ipv6_allonesaddr. Noted by Masayuki Ishikawa
2017-08-09 06:59:55 -06:00
neighbor
net/: Fix a sixlowpan typo bug recently introduced; Rename g_ipv6_allzeroaddre with the more meaning g_ipv6_unspecaddr since the all-zero address is the IPv6 unspecified address (sometime IN6_ADDR_ANY). Remove more inline tests for IPv6 multicast with tcommint net_is_addr_mcast() macro. Update some comments.

Makefile
This comment adds (1) basic support for AF_BLUETOOTH sockets. The logic compiles but is still incomplete. Support for Bluetooth is general is still dependent on CONFIG_EXPERMIMENTAL because it is not yet ready for used.
