@msherif1234 shall we name them dropped instead of deleted ? Also, will this count packets dropped

  1. if SW based recovery happens and acl drops the packets on port, egress queue
  2. if HW based recovery happens and HW drops packets on port, egress queue

we tried to use deleted instead of dropped to align with an existing similar field as stated in the PR description.
for either sw/hw recovery this will count the dropped packets and its orthogonal to acl drops
