rt2x00: reverse external PA capability flag logic
Consequently refer to external PA instead of inverting the logic and
use an internal PA capability flag which is a bit confusing.
Currently this is used for Rt3352 only, but MT7620A also allows for an
external PA which will be supported by a follow up patch.

Systems with 64 bit DMA at least partially require buffers to be used
for DMA to be 8-byte-aligned. One example is Amlogic Meson GX.
Switching the MMC/SDIO driver for this platform to SG DMA mode
resulted in problems due to unaligned buffers.
Fortunately the brcmfmac driver has a global define for the alignment.
Changing it to 8 fixed the issues with Meson GX.

gso: Support frag_list splitting with head_frag
A driver may use build_skb() for received packets.
These SKBs then have a head_frag.
Since commit d7e8883cfcf4 ("net: make GRO aware of
skb->head_frag"), GRO may build frag_list SKBs out of
head_frag received SKBs.
In such a case, the chained SKBs end up with a head_frag.
Commit 07b26c9454a2 ("gso: Support partial splitting at
the frag_list pointer") adds partial segmentation of frag_list
SKB chains into individual SKBs.
However, this is not done if the chained SKBs have any
linear part, because the device may not be able to DMA
the private linear buffer.
A chained frag_list SKB with head_frag is wrongfully
detected in this case as having a private linear part
and thus falls back to software GSO, while in fact the
linear part is backed by a DMA page just like any other frag.
This causes low performance when forwarding those packets
that were built with build_skb()
Allow partial segmentation at the frag_list pointer for
chained SKBs with head_frag.
Note that such SKBs can only be created by GRO, when applied
to received packets with head_frag.
Also note that this change only affects the data path that
performs the partial segmentation at frag_list pointer, and
not any of the other more common data paths.

In aarch64 system, the BD pointer is 64bit, and the high-order 32-bits
of the address is effective, so replace usigned with (void *) type to
aovid 64bit address is casted to 32bit in .fec_enet_get_nextdesc() and
.fec_enet_get_prevdesc() functions.

Merge branch 'l2tp-drop-l2tp_session_find'
