Subject: [PATCH bpf-next 0/2] nfp: bpf: improve offload checks

Hi,

this set adds check to make sure offload behaviour is correct.
First when atomic counters are used, we must make sure the map
does not already contain data we did not prepare for holding
atomics.

Second patch double checks vNIC capabilities for program offload
in case program is shared by multiple vNICs with different
constraints.
