The format is either "zd" or "zx". I misunderstood how you want to print
it, if you want hexadecimal, it should be "zx" then.

It would be worth doing something like:
#ifdef CADENCE_GEM_ERR_DEBUG
#define CADENCE_GEM_GATE 1
#else
#define CADENCE_GEM_GATE 0
#endif
#define DB_PRINT(...) do { \
if (CADENCE_GEM_GATE) { \
fprintf(stderr, ": %s: ", __func__); \
fprintf(stderr, ## __VA_ARGS__); \
} \
} while (0)
So these format strings don't go stale in and only get detected on
--debug builds.
While your at it I suspect the fprintf debug would be better of as:
qemu_log("%s: " fmt, __func__, ## args);

Indeed, or even see if it is worth converting to full-on trace points
for dynamic control of whether to catch these things without having to
recompile debug on or off.

HWADDR_PRIx is to use with hwaddr type (packet_desc_addr).
rx_desc_get_buffer() is uint64_t, you must use PRIx64.
It may be better to remove also the cast to unsigned.

Other places in the code also use HWADDR_PRIx with rx_desc_get_buffer().
Should I change them also ?

No, in fact you should change the return type of rx_desc_get_buffer() to hwaddr. Thanks, Laurent
