Similar to what we do when we remove a PCI function, set the QEDF_UNLOADING flag to prevent any requests from being queued while a vport is being deleted. This prevents any requests from getting stuck in limbo when the vport is unloaded or deleted. Fixes the crash: PID: 106676 TASK: ffff9a436aa90000 CPU: 12 COMMAND: "multipathd" #0 [ffff9a43567d3550] machine_kexec+522 at ffffffffaca60b2a #1 [ffff9a43567d35b0] __crash_kexec+114 at ffffffffacb13512 #2 [ffff9a43567d3680] crash_kexec+48 at ffffffffacb13600 #3 [ffff9a43567d3698] oops_end+168 at ffffffffad117768 #4 [ffff9a43567d36c0] no_context+645 at ffffffffad106f52 #5 [ffff9a43567d3710] __bad_area_nosemaphore+116 at ffffffffad106fe9 #6 [ffff9a43567d3760] bad_area+70 at ffffffffad107379 #7 [ffff9a43567d3788] __do_page_fault+1247 at ffffffffad11a8cf #8 [ffff9a43567d37f0] do_page_fault+53 at ffffffffad11a915 #9 [ffff9a43567d3820] page_fault+40 at ffffffffad116768 [exception RIP: qedf_init_task+61] RIP: ffffffffc0e13c2d RSP: ffff9a43567d38d0 RFLAGS: 00010046 RAX: 0000000000000000 RBX: ffffbe920472c738 RCX: ffff9a434fa0e3e8 RDX: ffff9a434f695280 RSI: ffffbe920472c738 RDI: ffff9a43aa359c80 RBP: ffff9a43567d3950 R8: 0000000000000c15 R9: ffff9a3fb09b9880 R10: ffff9a434fa0e3e8 R11: ffff9a43567d35ce R12: 0000000000000000 R13: ffff9a434f695280 R14: ffff9a43aa359c80 R15: ffff9a3fb9e005c0 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
