Subject: [PATCH net-next v10 04/12] netdevsim: access ->pp through netmem_desc instead of page
Date: Mon, 14 Jul 2025 21:00:39 +0900	[thread overview]
Message-ID: <20250714120047.35901-5-byungchul@sk.com> (raw)
In-Reply-To: <20250714120047.35901-1-byungchul@sk.com>

To eliminate the use of struct page in page pool, the page pool users
should use netmem descriptor and APIs instead.

Make netdevsim access ->pp through netmem_desc instead of page.
