refactors this code into be_vf_setup() and be_vf_clear().  The

Giuseppe CAVALLARO 45db81e159 stmmac: limit max_mtu in case of 4KiB and use __netdev_alloc_skb (V2)
Problem using big mtu around 4096 bytes is you end allocating (4096
+NET_SKB_PAD + NET_IP_ALIGN + sizeof(struct skb_shared_info) bytes ->
8192 bytes : order-1 pages

It's better to limit the mtu to SKB_MAX_HEAD(NET_SKB_PAD),
to have no more than one page per skb.

Also the patch changes the netdev_alloc_skb_ip_align() done in
init_dma_desc_rings() and uses a variant allowing GFP_KERNEL allocations
allowing the driver to load even in case of memory pressure.

Giuseppe CAVALLARO 286a837217 stmmac: add CHAINED descriptor mode support (V4)
This patch enhances the STMMAC driver to support CHAINED mode of
descriptor.

STMMAC supports DMA descriptor to operate both in dual buffer(RING)
and linked-list(CHAINED) mode. In RING mode (default) each descriptor
points to two data buffer pointers whereas in CHAINED mode they point
to only one data buffer pointer.

In CHAINED mode each descriptor will have pointer to next descriptor in
the list, hence creating the explicit chaining in the descriptor itself,
whereas such explicit chaining is not possible in RING mode.

First version of this work has been done by Rayagond.
Then the patch has been reworked avoiding ifdef inside the C code.
A new header file has been added to define all the functions needed for
managing enhanced and normal descriptors.
In fact, these have to be specialized according to the ring/chain usage.
Two new C files have been also added to implement the helper routines
needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

Anton Blanchard 13946f5e4e ehea: Merge swqe2 TSO and non TSO paths
write_swqe2_TSO and write_swqe2_nonTSO are almost identical.

For TSO we have to set the TSO and mss bits in the wqe and we only
put the header in the immediate area, no data. Collapse both
functions into write_swqe2_immediate.
