Currently actions are chained by a singly linked list,
therefore it is a bit hard to add and remove a specific
entry. Convert it to struct list_head so that in the
latter patch we can remove an action without finding
its head.

packet: deliver VLAN TPID to userspace
This patchset enables userspace to get VLAN TPID as well as the VLAN TCI.
After the 802.1AD support, userspace packet receivers (packet dumper,
software switch, and the like) need how to know VLAN TPID in order to
reconstruct original tagged frame.
v4: Simply use sizeof(tp_padding) for zeroing the padding bytes,
commented by David Laight.
Use __u16 for tp_vlan_tpid in tpacket_hdr_variant1,
commented by Daniel Borkmann.
v3: Add a definition which indicates whether tp_vlan_tpid is valid.
Explicitly define pad bytes for tpacket{2,3}_hdr and pick the area
for tp_vlan_tpid from the definition. Commented by David Laight.
v2: Add BUILD_BUG_ON() to make current aligned size of
struct tpacket{2,3}_hdr clear. Commented by Ben Hutchings.

struct tpacket{2,3}_hdr is aligned to a multiple of TPACKET_ALIGNMENT.
Explicitly defining and zeroing the gap of this makes additional changes
easier.

We may add members to them until current aligned size without forcing
userspace to call getsockopt(..., PACKET_HDRLEN, ...).

bna: Update the Driver to v3.2.23.0
This patch set consists of feature additions like s/w timestamping support,
multi-buffer RX, firmware patch simplification, enhancements for RX filters,
RX processing changes, bug fixes and updates the firmware version to v3.2.3.0.
The patch set addressed the review commnets recieved.
This patch set updates the BNA driver to v3.2.23.0 and was tested against
net-next 3.12.0-rc6 kernel.
====================

This patch includes change to enable firmware patch simplication feature.
This feature is targeted to address the requirement to have independent patch
release for firmware. Prior to the 3.2.3.0 firmware, releasing a patch fix for
firmware would require changes to bna driver, to use new firmware images.
However with these changes, if the new firmware is flashed on to the Adapter,
the driver will use the new firmware after checking the patch release byte in
the firmware version.
Update the f/w version to 3.2.3.0

Change details:
- When bnad_setup_tx() returns NULL, the error is NOT returned to the caller.
The caller will incorrectly assume success. So Return ENOMEM when bna_tx_create()
fails.
- If bnad_tx_msix_register() fails, call bna_tx_destroy() to free tx & to NULL
the bnad reference to tcb.

Currently we already check to see whether the BNAD_TXQ_TX_STARTED cleared.
But if the tcb structure which contains this flag is also already freed by that
time, we would dereference the NULL pointer. This patch is to check tcb for NULL
pointer, before dereferencing it.

Change Details:
- Prefetch header in GRO path. This reduces napi_frags_skb time from 9% to 5%.
- Changed the configurable limit of RxQ depth to 16384 (was 2048).
- bnad_rx_unmap_q elements are cachealigned.
