net: hns3: add debugfs support for interrupt coalesce
Since user may need to check the current configuration of the
interrupt coalesce, so add debugfs support for query this info.
Create a single file "coalesce_info" for it, and query it by
"cat coalesce_info", return the result to userspace.
For device whose version is above V3(include V3), the GL's register
contains usecs and 1us unit configuration. When get the usecs
configuration from this register, it will include the confusing unit
configuration, so add a GL mask to get the correct value, and add
a QL mask for the frames configuration as well.
The display style is below:
$ cat coalesce_info
tx interrupt coalesce info:
VEC_ID ALGO_STATE PROFILE_ID CQE_MODE TUNE_STATE STEPS_LEFT...
0 IN_PROG 4 EQE ON_TOP 0...
1 START 3 EQE LEFT 1...
rx interrupt coalesce info:
VEC_ID ALGO_STATE PROFILE_ID CQE_MODE TUNE_STATE STEPS_LEFT...
0 IN_PROG 3 EQE LEFT 1...
1 IN_PROG 0 EQE ON_TOP 0...
