[Ben] We can simply the code by defining these constants as bitmasks
instead, e.g.
T_CAPABILITY_MULTI_CS (1 << 0)
T_CAPABILITY_WIMAX (1 << 1)
T_CAPABILITY_QOS (1 << 2)
T_CAPABILITY_AGGREGATION (1 << 3)

Yes we could add a new option in Kconfig in consistence with other
drivers. There are also some debug messages displayed through dev_dbg()
and netdev_dbg(), that are controlled through CONFIG_DYNAMIC_DEBUG. Any
idea whether these should be also enclosed by GDM72XX_DEBUG, or left to
be handled separately by CONFIG_DYNAMIC_DEBUG only?
The capitals was a slip, thanks for spotting this. I'll submit an
updated patch to fix this too.

Ok, got it. With respect to rearrangements in code I assume you're
referring to dump_eth_packet() right? What do you recommend?

Double shifting here... It should just be:
val = T_CAPABILITY_WIMAX | T_CAPABILITY_MULTI_CS;
This bug feels like something a static checker should find. Let me test
that.

Ick, no, never put #ifdef in .c code if you can help it. For stuff like
this, just rely on the dynamic debug core and use the pr_debug and
dev_dbg() calls, like the driver is doing, so all should be fine.

This should be moved to use dev_dbg(), along with the other calls to
this function in this file.

But how about those cases where debug code consists of more than a
simple call to pr_debug() / dev_dbg()?
For instance consider dump_eth_packet(), defined in gdm_wimax.c. This
function is called every time a packet is received or transmitted, and
calls other helper functions too (get_protocol_name(),
get_ip_protocol_name(), get_port_name()).
Doesn't all this debug logic provide an overhead to the tx / rx functions?

Then that code is wrong :)

Yes, so much so it doesn't make sense to even have that type of
function, right?

But dev_dbg() gets eventually to be printk(), which cannot print the
buffer, so using print_hex_dump_debug() seems to be correct for this
case, no?

No, you don't want to print the message unless debugging is enabled, and
dev_dbg() uses the proper in-kernel dynamic debug infrastructure. There
should never be a separate config option for debugging a driver, that
ensures that no user will ever be able to help you out with it.
So delete the ifdef stuff, and the config option, and just use the
proper in-kernel infrastructure for this.

Ok, I agree on the ifdef stuff. My question was regarding your

You want the device name/id/label to show up as well, that is why you
should use the dev_dbg() version, print_hex_dump() does not take a
struct device *, so the user has no idea what device this data was
coming from.

But Michalis could alway add something like:
dev_hex_dump()
and
dev_dbg_hex_dump()

With the built-in "hex dump primitive" in printk(), why would you want
to do that? You shouldn't be putting more than 64 bytes in a single
printk message in a hex dump, if you want to do more, use debugfs.

%p*h doesn't also emit "ascii or dots" for one.
I agree %p*h should be preferred but people do
all sorts of strange things in debugging printks.
