Subject: [PATCH bpf-next v4 04/15] xsk: move defines only used by AF_XDP internals to xsk.h
Date: Wed, 20 May 2020 11:47:31 +0200	[thread overview]
Message-ID: <20200520094742.337678-5-bjorn.topel@gmail.com> (raw)
In-Reply-To: <20200520094742.337678-1-bjorn.topel@gmail.com>

From: Björn Töpel <bjorn.topel@intel.com>

Move the XSK_NEXT_PG_CONTIG_{MASK,SHIFT}, and
XDP_UMEM_USES_NEED_WAKEUP defines from xdp_sock.h to the AF_XDP
internal xsk.h file. Also, start using the BIT{,_ULL} macro instead of
explicit shifts.
