00335cd4-atl-38: netmap: predeclare the dev variable

Not doing this results in an error when building with linux 5.4:
netmap/LINUX/../sys/dev/netmap/netmap.c: In function 'netmap_grab_packets':
netmap/LINUX/../sys/dev/netmap/netmap.c:1226:17: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]

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.

Fix generic netmap driver for oversize HW rings

Devices can have ring parameters which are larger than the max which
netmap allows. To mitigate this we now use the generic_ring_size parameter,
instead of the HW ring size parameter in the case of oversized HW rings.

Fix assymetry in reference counter updates of memory allocator

When a single memory region was provided via the EXTMEM option multiple times, for multiple interfaces, then the memory region was never actually released by netmap. After closing all netmap file descriptors, the external memory remained in use by netmap.

The problem was in netmap_mem_drop: the condition to release the memory reference is when the last user of *netmap_adapter* is gone, not when the last user of *netmap_mem_d* is gone.
