zhhyu7 opened a new pull request, #17465:
URL: https://github.com/apache/nuttx/pull/17465
## Summary
1. convert Kconfig to variable, upperhalf can supports multiple working
modes at the same time, which is specified by NIC when register, the
multi-network card scenario will be more flexible;
2. add direct rx mode, avoid packet processing delays caused by task
switching, to support those applications that are extremely time-sensitive;
3. modify txavail to be sent directly in the current thread, avoid packet
processing delays caused by task switching too.
## Impact
All network card drivers implemented using ```struct netdev_lowerhalf_s```.
It is necessary to initialize appropriate rxtype and priority according to
the business scenario during network card initialization.
## Testing
sim:matter with ping and iperf2.
