Subject: [PATCH net-next 00/18] refactor duplicate codes in the qdisc class walk function
The walk implementation of most qdisc class modules is basically the
same. That is, the values of count and skip are checked first. If count
is greater than or equal to skip, the registered fn function is
executed. Otherwise, increase the value of count. So the code can be
refactored.
The walk function is invoked during dump. Therefore, test cases related
to the tdc filter need to be added.
Add test cases locally and perform the test. The test results are listed
below:
