Subject: [PATCH net-next 08/13] sfc: Preserve rx_frm_trunc counters when resizing
 DMA rings

From: Ben Hutchings <bhutchings@...arflare.com>

We allocate efx_channel structures with kzalloc() so we don't need to
zero-initialise individual fields in efx_probe_channel().  Further,
this function will be called again during DMA ring resizing and we
should not reset any statistics then.
