From: Dmitry Fleytman <dmitry.fleyt...@ravellosystems.com>
This patch introduces a handful macros
for tracing of Ethernet addresses.
There are 2 reasons for those macros to be added:
1. They will be used by future commits
introducing e1000e device emulation;
2. They fix vmxnet3 build with debug tracing enabled:
When vmxnet3 configuration tracing enabled by uncommenting
VMXNET_DEBUG_CONFIG definition in vmxnet_debug.h, following
compilation error is observed:
hw/net/vmxnet3.c: In function ‘vmxnet3_net_init’:
hw/net/vmxnet3.c:1974:52: error: expected ‘)’ before ‘MAC_FMT’
VMW_CFPRN("Permanent MAC: " MAC_FMT, MAC_ARG(s->perm_mac.a));
^
hw/net/vmxnet3.c:1974:17: error: format ‘%s’ expects a matching ‘char *’
argument [-Werror=format=]
VMW_CFPRN("Permanent MAC: " MAC_FMT, MAC_ARG(s->perm_mac.a));
^
hw/net/vmxnet3.c:1974:17: error: format ‘%s’ expects a matching ‘char *’
argument [-Werror=format=]
cc1: all warnings being treated as errors
