The LED2[2]/INTn pin on Marvell 88E1318S as well as 88E1510/12/14/18 needs
to be configured to be usable as interrupt not only when WOL is enabled,

When changing network interface settings, Windows guests
older than WS2016 can no longer shutdown. This was addressed
by commit 0ef58b0a05c12 ("hv_netvsc: change GPAD teardown order

guests that share NVSP protocol versions with WS2016 gue
Guests running on WS2012 hosts would not shutdown when changing network
interface setting (e.g. Number of channels, MTU ... etc).
This patch series addresses these shutdown issues we enecountered with WS2012
hosts. It's essentialy a rework of the series sent in
https://lkml.org/lkml/2018/1/23/11
Split each of the functions into two for each of send/recv buffers.
This will be needed in order to implement a fine-grained messaging

different Windows versions

Prior to commit 0cf737808ae7 ("hv_netvsc: netvsc_teardown_gpadl() split")

2- Teardown receive buffer GPADL
3- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF messa

In case memory resources for fw were succesfully allocated, release

Nope. The whole idea is that they behave like normal linux
interfaces. So there is no need to document them. You already know how
to use them.

Wrong.

Hi Davide,
Our overnight tc test runs of net-next revealed a kernel bug on one of
the BPF tests you submitted, d959. The add action completes
successfully, but the bug occurs on the verify when tdc does a get of
the action that was just added. Here's the text of the dump:

hi,
eBPF programs loaded for kprobes are allowed to read kernel
internal structures. We check the provided kernel version
to ensure that the program is loaded for the proper kernel.
The problem is that the version check is not enough, because
it only follows the version setup from kernel's Makefi
And renaming it into parse_notes_buildid to be more
precise and usable in following patches.

Adding fetch_kernel_buildid helper function to
retrieve build id from running kernel. It will
be used in following patches.

Adding filechk2 function that has the same semantics
as filechk, but it takes the target file from the 2nd
argument instead of from the '$@' as in the filechk
function.
This function is needed when we can't have separate
target for the file, like in the following patch.

There's no need to pass LD* arguments to link-vmlinux.sh,
because they are passed as variables. The only argument
the link-vmlinux.sh supports is the 'clean' argument.
