[PATCH nft 03/14] tests/shell: skip map query if kernel lacks support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Florian Westphal <fw@xxxxxxxxx>

On recent kernels one can perform a lookup in a map without a destination
register (i.e., treat the map like a set -- pure existence check).

Add a feature probe and work around the missing feature in
typeof_maps_add_delete: do the test with a simplified ruleset,

Indicate skipped even though a reduced test was run (earlier errors
cause a failure) to not trigger dump validation error.
