Subject: [Intel-wired-lan] [PATCH net-next 9/9] i40e: Simplify memory allocation functions
Date: Tue, 26 Sep 2023 20:27:10 +0200	[thread overview]
Message-ID: <20230926182710.2517901-10-ivecera@redhat.com> (raw)
In-Reply-To: <20230926182710.2517901-1-ivecera@redhat.com>

Enum i40e_memory_type enum is unused in i40e_allocate_dma_mem() thus
can be safely removed. Useless macros in i40e_alloc.h can be removed
as well.
