patch subject: [PATCH net-next v2 2/6] virtio_net: Remove command data from
control_buf
config: x86_64-randconfig-122-20240328
(https://download.01.org/0day-ci/archive/20240329/202403290542.gm5d7hmg-...@intel.com/config)
compiler: clang
Allocate memory for the data when it's used. Ideally the could be on the
stack, but we can't DMA stack memory. With this change only the header
and status memory are shared between commands, which will allow using a
tighter lock than RTNL.
