drivers/net/mlx4: Use %pV, pr_, printk_once

2010-07-16T02:05:17+00:00

Remove near duplication of format string constants by using the newly
introduced vsprintf extention %pV to reduce text by 20k or so.

$ size drivers/net/mlx4/built-in.o*
   text	   data	    bss	    dec	    hex	filename
 161367	   1866	  48784	 212017	  33c31	drivers/net/mlx4/built-in.o
 142621	   1866	  46248	 190735	  2e90f	drivers/net/mlx4/built-in.o.new

Use printk_once as appropriate.
Convert printks to pr_, some bare printks now use pr_cont.
Remove now unused #define PFX.

mlx4: add dynamic LRO disable support

2010-06-29T06:04:10+00:00

This patch adds dynamic LRO diable support for mlx4 net driver.
It also fixes a bug of mlx4, which checks NETIF_F_LRO flag in rx
path without rtnl lock.

(I don't have mlx4 card, so only did compiling test. Anyone who wants
to test this is more than welcome.)

This is based on Neil's initial work too, and heavily modified based
on Stanislaw's suggestions.

mlx4_en: use net_device dev_id to indicate port number

2010-05-31T07:27:45+00:00

Today, there are no means to know which port of a hardware device a netdev
interface uses. struct net_device conatins a field, dev_id, that can be used
for that. Use this field to save the port number in ConnectX that is being used
by the net device; port numbers are zero based.

drivers/base: Convert dev->sem to mutex

2010-05-21T16:37:30+00:00

The semaphore is semantically a mutex. Convert it to a real mutex and
fix up a few places where code was relying on semaphore.h to be included
by device.h, as well as the users of the trylock function, as that value
is now reversed.

mlx4_core: Clean up mlx4_alloc_icm() a bit

2010-05-20T22:58:22+00:00

Handle the allocation error case first, so that we don't have further
nested if for handling the common case of success.

mlx4_core: Fix possible chunk sg list overflow in mlx4_alloc_icm()

2010-05-20T22:58:22+00:00

If the number of sg entries in the ICM chunk reaches MLX4_ICM_CHUNK_LEN,
we must set chunk to NULL even for coherent mappings so that the next
time through the loop will allocate another chunk.  Otherwise we'll
overflow the sg list the next time through the loop.  This will lead to
memory corruption if this case is hit.

mthca does not have this bug.

drivers/net: Remove unnecessary returns from void function()s

2010-05-14T07:19:28+00:00

This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

It also does not remove null void functions with return.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

with some cleanups by hand.

Compile tested x86 allmodconfig only.
