The driver needs to verify the eeprom checksum and firmware crc status bits,
and shutdown the driver if they fail. This code stops the processing of traffic,
but doesn't kill the PF netdev so that the NVMUpdate process should still have a
chance at fixing the image. The eeprom is checked on driver load and after an
EMP reset, the latter of which should be generated after an NVMUpdate.

The Tx watchdog handler runs in interrupt context, so it would cause an

Instead, set a flag and let the reset task handle sending the request.

Prior to cd14ef54 (igb: Change to use statically allocated array for
MSIx entries), having msix_entries different from NULL was an indicator
that MSIX is enabled.
In igb_set_interrupt_capabiliy we may fall back to MSI-only. Prior to
the above patch msix_entries was set to NULL by
igb_reset_interrupt_capability.

However, now we are checking the flag for IGB_FLAG_HAS_MSIX and so the
stack gets completly confused:

When igb_set_interrupt_capability() calls
igb_reset_interrupt_capability() (e.g., because CONFIG_PCI_MSI is unset),
num_q_vectors has been set but no vector has yet been allocated.

igb_reset_interrupt_capability() will then call igb_reset_q_vector,
which assumes that the vector is allocated. As this is not the case, we
are accessing a NULL-pointer.

This patch fixes it by checking that q_vector is indeed different from
NULL.

This patch fixes flow control autonegotiation for KR/KX/K4 interfaces.
When setting up MAC link, the cached autoc value and current autoc value
were being incorrectly used to determine whether link reset is required.
This resulted in the driver ignoring and discarding flow control

when the mac was being setup.

This patch also splits the assignments for the 3 autoc variables into
their own block, and adds a comment explaining what each one means, in
