This patch resolves an issue where the driver will display incorrect info
for Q/SFP+ modules that were inserted after the driver has been loaded.

This patch adds a call to identify_phy() in ixgbe_get_settings() prior to
calling get_link_capabilities() which needs the PHY data in order to
determine the correct settings.

QSFP+ modules do not support auto negotiation and should advertise only
one speed at a time.

This patch adds logic in ethtool to allow setting and reporting the
advertised speed at either 1Gbps or 10Gbps, but not both. Also limits
the speed set in ixgbe_sfp_link_config_subtask() to highest supported.
Previously the link was set to whatever the supported speeds were.

When a VM is providing an iSCSI target and the LUN is used by the
backend domain, the generated skbs for direct I/O writes to the disk
have large, multi-page skb->data but no frags.

With some lengths and starting offsets, xen_netbk_count_skb_slots()
would be one short because the simple calculation of
DIV_ROUND_UP(skb_headlen(), PAGE_SIZE) was not accounting for the
decisions made by start_new_rx_buffer() which does not guarantee
responses are fully packed.

For example, a skb with length < 2 pages but which spans 3 pages would
be counted as requiring 2 slots but would actually use 3 slots.

skb->data:

    |        1111|222222222222|3333        |

Fully packed, this would need 2 slots:

    |111122222222|22223333    |

But because the 2nd page wholy fits into a slot it is not split across
slots and goes into a slot of its own:

    |1111        |222222222222|3333        |

Miscounting the number of slots means netback may push more responses
than the number of available requests.  This will cause the frontend
to get very confused and report "Too many frags/slots".  The frontend
never recovers and will eventually BUG.

Fix this by counting the number of required slots more carefully.  In
xen_netbk_count_skb_slots(), more closely follow the algorithm used by
xen_netbk_gop_skb() by introducing xen_netbk_count_frag_slots() which
is the dry-run equivalent of netbk_gop_frag_copy().

Based partially on MS standard spec quotes from Alex Dubov.

As any code that works with user data this driver isn't recommended to use
to write cards that contain valuable data.

It tries its best though to avoid data corruption and possible damage to
the card.
