Support STP parameters in bridge
Added basic support for some basic spanning tree protocol configuration parameters on the bridge device.
Notes:
- I am very new to Go, so if I am deviating from any idioms or best practices please let me know and I will do my best to correct.
- When I run the full
go-netlinktest suite some of the tests fail due to parameter off-by-one issues. I am running linux kernel 5.11.10 at the time of writing. I don't know why this is happening for me but I will assume this is not happening elsewhere until I dig in a little more and find out what is going on. I mention this here because I deliberately wrote a couple more tests which fail for similar off-by-one issues under the assumption that they won't fail on other machines. I am leaving this as a draft PR till I find out what is going on.
Warning:
My colleague ran the tests I included in this patch on his machine (running linux kernel 5.4) and all tests pass.
I am upgrading this PR from draft in the hopes that others will run the tests included in this patch and confirm.
I suggest that we make a point of running this test suite on various linux kernels.
The tests fail for me on kernel 5.11.10
The failure symptom is that all timer values I specify are accepted by the kernel (assuming they were otherwise valid). However, on query every timer is reported as the specified value less one. E.g., if I specify the max age stp parameter as 200 then the operation is is accepted but on querying the current value it returns as 199.
