From dbb9d619941ad57dbe3c6667764e1eccd5ee5f1b Mon Sep 17 00:00:00 2001 From: David Kershner Date: Mon, 15 Jun 2015 23:31:58 -0400 Subject: [PATCH] staging: unisys: define structures outside of iochannel During testing with visornic the offset of num_rcv_bufs was being reported at 188 instead of 186. The vnic structure starts at 180 and the macaddr is only 6 bytes long. When I defined and packed the structures outside of the struct and then referenced them in the struct the correct offset was generated.
