Subject: [PATCH v6 net-next 03/15] net: Use __napi_alloc_frag_align() instead of open coding it.
Date: Wed, 12 Jun 2024 18:44:29 +0200

The else condition within __netdev_alloc_frag_align() is an open coded
__napi_alloc_frag_align().

Use __napi_alloc_frag_align() instead of open coding it.
Move fragsz assignment before page_frag_alloc_align() invocation because
__napi_alloc_frag_align() also contains this statement.
