Update for 6.1.27 linux kernel

* Regenerate the vanilla-ice patch since the one from the atl tarball
  did not properly apply and needed changes for upstream.
* Update ice_netmap_linux.h for a type change. Upstream has some
  more changes but these have been skipped.
* Update netmap_linux.c for a function removal.
* Update netmap.c for a type change.
* Add configure tests so that netmap can support building
  between newer and older kernels with these code changes.
