From: Huisong Li <[email protected]>Currently, the VF LSC capability is obtained from PF driver in the interrupt mailbox interrupt thread, it is asynchronous. The VF driver waits for 500ms to get this capability in probe process. The primary process will receive a message and do probe in the interrupt thread context when attach a device in the secondary process. At this case, VF driver never obtains this capability from PF. The root cause is that 'vf->pf_push_lsc_cap' is not updated by the handling mailbox thread until finishing probe. The reason this update wouldn't be done is that the handling mailbox interrupt thread and the probe alarm thread are both in epool thread, and the probe alarm thread is before the mailbox interrupt thread.

Applied to dpdk-next-net/main, thanks.
