net: tulip: delete useless tests on netdev_priv · 2d4dda78

由 Julia Lawall 提交于 1月 02, 2014

Netdev_priv performs an addition, not a pointer dereference, so it seems
quite unlikely that its result would ever be NULL.

A semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

statement S;
@@

- if (!netdev_priv(...)) S

mlx4_en: Only cycle port if HW timestamp config changes · 2156d9a8

由 Shawn Bohrer 提交于 12月 31, 2013

If the hwtstamp_config matches what is currently set for the device then
simply return.  Without this change any program that tries to enable
hardware timestamps will cause the link to cycle even if hardware
timstamps were already enabled.

mlx4_en: Add PTP hardware clock · ad7d4eae

由 Shawn Bohrer 提交于 12月 31, 2013

This adds a PHC to the mlx4_en driver. We use reader/writer spinlocks to
protect the timecounter since every packet received needs to call
timecounter_cycle2time() when timestamping is enabled.  This can become
a performance bottleneck with RSS and multiple receive queues if normal
spinlocks are used.

This driver has been tested with both Documentation/ptp/testptp and the
linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox
ConnectX-3 card.

hamradio: 6pack: fix error return code · 769f01ef

由 Julia Lawall 提交于 12月 29, 2013

Set the return variable to an error code as done elsewhere in the function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>

if@p1 (\(ret < 0\|ret != 0\))

ret@p1 = 0
