Michael Chan says:

====================
bnxt_en: Bug fixes.

Miscellaneous bug fix patches, including two resource handling fixes for
the RDMA driver, a PCI shutdown patch to add pci_disable_device(), a patch
to fix ethtool selftest crash, and the last one suppresses an unnecessry
error message.

Please also queue patches 1, 2, and 3 for -stable.  Thanks.
