below command to create mbim NIC on host
nsh> conn 3
NuttX's MBIM device implementation adds an additional MBIM network
card to the NuttX system, which can debug the data communication with
the host, but this network card is unnecessary and needs to be removed
when the business actually uses this driver, And the cdcncm_receive
method needs to be re-implemented.

Summary:
Because stdio.h references stdatomic.h in MVSC, it internally declares mbstate_t, leading to redeclarations during compilation.
Signed-off-by: chenrun1 <chenrun1@xiaomi.com>
Summary:
This change mainly appears in the compilation environment of MVSC
Since MVSC supports the c++11 standard in VS2019 preview3 (https://en.cppreference.com/w/cpp/compiler_support/11), we can do static initialization using the c++11 approach

This is a tool for associating discrete IDs with addresses.
This tool is implemented through the red-black tree method provided by <sys/tree.h>, and the time complexity when calling, searching, and deleting is optimized to O(logn)
The implementation is the moving node operation of two red-black trees
1. When applying for a node, it will first check whether there is an available node in the "removed" tree. If so, the memory address of the node will be reused and moved to the "alloced" tree.
2. If the "removed" tree is an "empty tree", then the node will be requested from the memory and added to the "alloced" tree
3. Similarly, when removing a node, we set the address pointed to in the node to "NULL" and move it to the "removed" tree. Next time we alloc the node, we can reduce the overhead caused by memory application
For now, we still have something that can be optimized, and that is the memory elimination mechanism of the "removed tree". The current implementation will only release all the content under the "removed" tree when the idtree is destroyed.

According to the eMMC specification, in Backwards Compatibility
with legacy MMC card mode, the frequency of the SD clock must be
0-26 MHZ; in high speed SDR mode, it must be 0-52MHZ. So we should
switch to high speed SDR mode if the clock frequency is higher than
26MHZ.

CANIOC_GET_BITTIMING is now bidirectional: user specifies type field
