[ Upstream commit fde2f2d7f23d39f2fc699ba6d91ac3f4a2e637ca ]
When updating the SA, use the new update_pn flags instead of comparing the new PN with the initial one.
Comparing the initial PN value with the new value will allow the user to update the SA using the initial PN value as a parameter like this: $ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \ ead3664f508eb06c40ac7104cdae4ce5 $ ip macsec set macsec0 tx sa 0 pn 1 off
