Subject: [PATCH net-next 0/6] mlxsw: Two sampling fixes

From: Ido Schimmel <idosch@...dia.com>

This patchset fixes two bugs in recent sampling submissions.

The first fix, in patch #3, prevents matchall rules with sample action
to be added in front of flower rules on egress. Patches #1-#2 are
preparations meant at avoiding similar bugs in the future. Patch #4 is a
selftest.

The second fix, in patch #5, prevents sampling from being enabled on a
port if already enabled. Patch #6 is a selftest.

Ido Schimmel (6):
  mlxsw: spectrum_matchall: Perform protocol check earlier
  mlxsw: spectrum_matchall: Convert if statements to a switch statement
  mlxsw: spectrum_matchall: Perform priority checks earlier
  selftests: mlxsw: Test matchall failure with protocol match
  mlxsw: spectrum: Veto sampling if already enabled on port
  selftests: mlxsw: Test vetoing of double sampling
