508b4cf39b modules/mqnic/: Make number of allocated queue entries configurable via module parameters 
This may be complemented or replaced by making use of the appropriate ethtool
API in the future, of course.

f5f40297e3 modules/mqnic/: Fix, need to initialize per instance mutex before netdev registration 
struct mqnic::state_lock is used in netdev callbacks, which go "live"
after a netdev has been registered (via mqnic_init_netdev()).

60c2b6745d modules/mqnic/: Fix and enhance Makefile 
- Apply "Shared Makefile" style as found in [1]
- Especially but not only for cross compilation:
  - Accept commonly used variable KDIR to specify kernel build directory
  - Additionally accept KERNEL_SRC (instead of KDIR) as used by PetaLinux/Yocto
- Route all usual external module targets through to Kbuild
- Provide "install" target as shortcut for module installation
- Use $(MAKE) as recommended in [2]

[1] https://www.kernel.org/doc/html/latest/kbuild/modules.html, section 3.1
[2] https://www.gnu.org/software/make/manual/make.html#MAKE-Variable, section 5.7.1.
