Subject: [PATCH net-next 07/12] net: airoha: ppe: Remove airoha_ppe_is_enabled() where not necessary
Date: Wed, 15 Oct 2025 09:15:07 +0200	[thread overview]
Message-ID: <20251015-an7583-eth-support-v1-7-064855f05923@kernel.org> (raw)
In-Reply-To: <20251015-an7583-eth-support-v1-0-064855f05923@kernel.org>

Now each PPE has always PPE_STATS_NUM_ENTRIES entries so we do not need
to run airoha_ppe_is_enabled routine to check if the hash refers to
PPE1 or PPE2.
