net/netdev: fix switch case missing break
Signed-off-by: chao.an <anchao@xiaomi.com>
```
Note: some applications like mbedtls uses F_GETFL to confirm
the nonblock-ness of the socket. This is critical for such
applications.
Fix the arp address changed if netdev renew, since the
arp table should be cleared when the netdev carrier off

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

This makes the user interface a little hostile. People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header). A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length. Instead, we define the packet buffer size then derive the MTU.
The MTU is not common currency in networking. On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP). Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes. So we should be all good and without the recurring 14 byte error in MTU's and MSS's.
Squashed commit of the following:
Trivial update to fix some spacing issues.
net/: Rename several macros containing _MTU to _PKTSIZE.
net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE. This is not the MTU which does not include the size of the link layer header. This is the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename the file d_mtu in the network driver structure to d_pktsize. That value saved there is not the MTU. The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header. The MTU does not include the link layer header.

Squashed commit of the following:
wireless/bluetooth: Some small changes that gets to a clean compile by just eliminating some incorrect implementations (still with a lot of warnings. The logic is still incomplete but now not so lethal.
wireless/bluetooth: Restructuring: Connection interfaces should internal to wireless/bluetooth. include/nuttx/wireless/bt_conn.h removed and merged with wireless/bluetooth/bt_conn.h. Several fix to get closer to bt_netdev.c compiling. Need to design some not interfaces and use some existing interfaces to send and receiv packets.
wireless/bluetooth: Some organization with some network device compile errors fixed. Still not even close to compiling.
net/bluetooth: Fix numerous compile issues; Still open design issues with regard to the interface with the Bluetooth stack.
wireless/bluetooth: Create bt_netdev.c with a crude copy of mac802154_netdev.c. Does not not even compile yet.
include/nuttx/net: Add bluetooth.h. Content is not yet correct.
net/netpackets: Add bluetooth.h. Update net/bluetooth to use new socket address definition.
net/bluetooth: Some fixes for initial build.
net/bluetooth: Add initial support for Bluetooth sockets. The initial cut is just the a clone of the IEEE 802.15.4 socket support with name changes.
net/ieee802154: Fix some typos noted when cloning to create net/bluetooth.
psock_close() and net_close() are internal OS functions and should not set the errno variable.
psock_ioctl() and netdev_ioctl() are internal OS functions and should not set the errno variable.
net_dupsd() and net_dupsd2() are internal OS functions and should not set the errno variable.
net/ and fs/: net_vfcntl(), file_fcntl(), file_dup(), and file_dup2() are all internal OS interfaces and should not modify the errno value.
This would be particularly useful, for example, in the case where there is only a single network adaptor and you want all output packets to go to the single adaptor in all cases. So for that behavior you could add a read-only routing table to the board-specific long that contains a single entry, the default route: 0.0.0.0/0.
Squashed commit of the following:
net/route: RAM and ROM routing tables build correctly in all IPv4 and IPv6 configurations.
net/route: Verify IPv6 ROM route build; Make number of ROM routes a variable, not a configuration item.
net/route: Add initial support for ROM-base, read-only routing tables.
net/route: Adjust and generalize some structures, rename some functions, and add configuration and build support that will eventually support read-only routing tables.
net/route: Some initial though experiments on use of a fixe, read-only routing table
Networking: Add implementation of logic for SIOCGIFCONF and SIOCGLIFCOF IOCTL commnds.
Networking: Add definitions and stuctures to support SIOCGIFCONF and SIOCGLIFCONF IOCTL commands.
