[PATCH 2/2] hv_netvsc: Print value of invalid ID in netvsc_send_{completion,tx_complete}()
From: Andrea Parri (Microsoft)
Date: Thu Apr 07 2022 - 00:43:16 EST
That being useful for debugging purposes.
Notice that the packet descriptor is in "private" guest memory, so
that Hyper-V can not tamper with it.
While at it, remove two unnecessary u64-casts.
