[dpdk-stable] "net/hns3: fix VF handling LSC event in secondary process" incompatible with 19.11.x

[Christian Ehrhardt]

Hi,
this mostly is an FYI to document why a change was not applied to the
stable series. This was targeted for stable releases:

    net/hns3: fix VF handling LSC event in secondary process

But it triggers

../drivers/net/hns3/hns3_mbx.c: In function ‘hns3_handle_mbx_msg_out_intr’:
../drivers/net/hns3/hns3_mbx.c:355:4: warning: implicit declaration of
function ‘hns3_handle_mbx_response’; did you mean
‘hns3_handle_msix_error’? [-Wimplicit-function-declaration]
  355 |    hns3_handle_mbx_response(hw, req);
      |    ^~~~~~~~~~~~~~~~~~~~~~~~
      |    hns3_handle_msix_error


This is due to missing:

    net/hns3: fix possible mismatched response of mailbox

And this one I already called out as a "help for backport" 12 days ago.

The same is true for:

../drivers/net/hns3/hns3_mbx.c:385:10: warning: implicit declaration
of function ‘rte_thread_is_intr’; did you mean ‘rte_thread_setname’?
[-Wimplicit-function-declaration]
  385 |         !rte_thread_is_intr()) && hns->is_vf;
      |          ^~~~~~~~~~~~~~~~~~
      |          rte_thread_setname

Which needs

    eal/windows: add interrupt thread skeleton

FYI for now I'll also drop dbbbad23e380773b37872df2195c4529fd93ca6f from 19.11.x
