New Revision: 366518
URL: https://svnweb.freebsd.org/changeset/base/366518
Log:
Properly cleanup driver during remove_one() in mlx5core.
Cleanup all host resources, SYSCTLs, MSIX vectors and memory used
by the host and only leave the device allocated memory behind, if any,
because it may still be in use, when the PCI remove function is called.
Else future probe calls may fail due to SYSCTLs already existing.
