[PATCH 11/15] mpt3sas: Report Firmware Package Version from HBA Driver.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Added function _base_display_fwpkg_version, which sends FWUpload
request to pull FW package version from FW Image Header.
Now driver prints FW package version in addition to FW
version if the PackageVersion is valid.
