Even though the device might be in MFP mode, if there's only one partition
enabled, then we still have plenty of interrupts for managing the Flow
Directory Sideband activity. This patch enables FD SB in this case.
This patch also reverses the sense of the conditional in order to remove
the negative logic.

By design, when no default MAC addresses are set in the Hypervisor for VFs,
the VFs are passed zero-macs. When such a MAC is received by the VF, it
generates a random MAC address and registers that MAC address
with the Hypervisor.
This random mac generation is currently done in the mlx4_en module.
There is a problem, though, if the mlx4_ib module is loaded by a VF before
the mlx4_en module. In this case, for RoCE, mlx4_ib will see the un-replaced
zero-mac and register that zero-mac as part of QP1 initialization.
Having a zero-mac in the port's MAC table creates problems for a
Baseboard Management Console. The BMC occasionally sends packets with a
zero-mac destination MAC. If there is a zero-mac present in the port's
MAC table, the FW will send such BMC packets to the host driver rather than
to the wire, and BMC will stop working.
To address this problem, we move the replacement of zero-mac addresses
with random-mac addresses to procedure mlx4_slave_cap(), which is part of the
driver startup for VFs, and is before activation of mlx4_ib and mlx4_en.
As a result, zero-mac addresses will never be registered in the port MAC table
by the driver.
In addition, when mlx4_en does initialize the net device, it needs to set
the NET_ADDR_RANDOM flag in the netdev structure if the address was
randomly generated. This is done so that udev on the VM does not create
a new device name after each VF probe (VM boot and such). To accomplish this,
we add a per-port flag in mlx4_dev which gets set whenever mlx4_core replaces
a zero-mac with a randomly-generated mac. This flag is examined when mlx4_en
initializes the net-device.

This patch implement the pci_error_handlers for mlx5_core which allow the
driver to recover from PCI error.
Once an error is detected in the PCI, the mlx5_pci_err_detected is called
and it:
1) Marks the device to be in 'Internal Error' state.
2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes
with error.
3) Returns all the on going commands with error.
4) Unloads the driver.
Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it
enables the device and restore it's pci state.
If the later succeeds, mlx5_pci_resume is called, and it loads the SW
stack.

Also add a new function update_link_info which updates the module_types
parameter and then calls get_link_info. This function should be called
in place of get_link_info so that the module_types variable stays

The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes
specified in table 33 of SFF-8436 as these have been accurate.

don't try to configure the device further if it failed. Additionally,
explicitly clear the INIT bit when we free VF resources, so that this

On EF10, MC_CMD_VPORT_RECONFIGURE can cause a CODE_MC_REBOOT event
to be sent to a function without incrementing the (adapter-wide)
warm_boot_count. In this case, the reboot is not detected by the
loop on efx_mcdi_poll_reboot(), so prepare for recovery from an MC
reboot anyway. When this codepath is run, the MC has always just
rebooted, so this recovery is valid.
The loop on efx_mcdi_poll_reboot() is still required for other MC
reboot cases, so that actions in response to an MC reboot are
performed, such as clearing locally calculated statistics.
