sky2_phy_reinit is called by the ethtool helpers sky2_set_settings,
sky2_nway_reset and sky2_set_pauseparam when netif_running.
However, at the end of sky2_phy_init GM_GP_CTRL has GM_GPCR_RX_ENA and
GM_GPCR_TX_ENA cleared. So, doing these commands causes the device to
stop working:
$ ethtool -r eth0
$ ethtool -A eth0 autoneg off
Fix this issue by enabling Rx/Tx after running sky2_phy_init in
sky2_phy_reinit.

Turning on memory debugging showed there could be page breaks in
hardware headers. OSA does not allow this so we had to add code
to bounce the header in case there is a page break. This patch also
fixes a problem in case the skb->data part of a fragmented skb
spreads multiple pages.

This patch adds a debug area for each qeth card. This debug area will replace
various other debug areas that are global for all cards handled by the device
driver. On crash dump analysis this makes life easier when trying to find out
what's going on with an interface. Also, the forest of debug areas for this
device driver is significantly cleared up.

Use u64_stats_sync infrastructure to provide 64bit rx/tx
counters even on 32bit hosts.
It is safe to use a single u64_stats_sync for rx and tx,

To properly implement 64bits network statistics on 32bit or 64bit hosts,
we provide one new type and four methods, to ease conversions.
Stats producer should use following template granted it already got an
exclusive access to counters (include/linux/u64_stats_sync.h contains
some documentation about details)
u64_stats_update_begin(&stats->syncp);
stats->bytes64 += len;
stats->packets64++;
u64_stats_update_end(&stats->syncp);
While a consumer should use following template to get consistent
snapshot :
u64 tbytes, tpackets;
unsigned int start;
do {
start = u64_stats_fetch_begin(&stats->syncp);
tbytes = stats->bytes64;
tpackets = stats->packets64;
} while (u64_stats_fetch_retry(&stats->lock, syncp));

netif_needs_gso() is checked twice in the TX path once,
before submitting the skb to the qdisc and once after
it is dequeued from the qdisc just before calling
ndo_hard_start(). This opens a window for a user to
change the gso/tso or tx checksum settings that can
cause netif_needs_gso to be true in one check and false
in the other.
Specifically, changing TX checksum setting may cause
the warning in skb_gso_segment() to be triggered if
the checksum is calculated earlier.
This consolidates the netif_needs_gso() calls so that
the stack only checks if gso is needed in
dev_hard_start_xmit().

early-receive is enabled (via ERT register) on these parts. Use packet

It has been reported that the new UFO software fallback path
fails under certain conditions with NFS. I tracked the problem
down to the generation of UFO packets that are smaller than the
MTU. The software fallback path simply discards these packets.
This patch fixes the problem by not generating such packets on
the UFO path.

Added new CAIF protocol type CAIFPROTO_DEBUG for accessing
CAIF debug on the ST Ericsson modems.
There are two debug servers on the modem, one for radio related
debug (CAIF_RADIO_DEBUG_SERVICE) and the other for
communication/application related debug (CAIF_COM_DEBUG_SERVICE).
The debug connection can contain trace debug printouts or
interactive debug used for debugging and test.
Debug connections can be of type STREAM or SEQPACKET.
