====================
10GbE Intel Wired LAN Driver Updates 2018-05-17

This series contains updates to ixgbe, ixgbevf and ice drivers.

Cathy Zhou resolves sparse warnings by using the force attribute.

Mauro S M Rodrigues fixes a bug where IRQs were not freed if a PCI error
recovery system opts to remove the device which causes
ixgbe_io_error_detected() to return PCI_ERS_RESULT_DISCONNECT before
calling ixgbe_close_suspend() which results in IRQs not freed and
crashing when the remove handler calls pci_disable_device().  Resolved
this by calling ixgbe_close_suspend() before evaluating the PCI channel
state.

Pavel Tatashin releases the rtnl_lock during the call to
ixgbe_close_suspend() to allow scaling if device_shutdown() is
multi-threaded.

Emil modifies ixgbe to not validate the MAC address during a reset,
unless the MAC was set on the host so that the VF will get a new MAC
address every time it reloads.  Also updates ixgbevf to set
hw-&gt;mac.perm_addr in order to retain the custom MAC on a reset.

Anirudh updates the ice NVM read/erase/update AQ commands to align with
the latest specification.
