linux-toradex.git/Documentation/networking/gianfar.txt, branch v3.16.7 Linux kernel for Apalis and Colibri modules gianfar: Remove sysfs stubs for FIFOCFG and stashing 2014-02-18T20:03:02+00:00 Claudiu Manoil claudiu.manoil@freescale.com 2014-02-17T10:53:15+00:00 34018fd419f1ca364bbd509e937357a5e05289ff Removing the sysfs stubs for the Tx FIFOCFG and ATTRELI (stashing) config registers, as these registers may only be configured after a MAC reset, with the controller stopped (i.e. during hw init, at probe() time). The current sysfs stubs allow on-the-fly updates of these registers (the locking measures are useless and only add unecessary code). Changing these registers is discouraged. Only the default values will be used instead. Moreover, the stashing (ATTRELI) configuration options were effectively disabled (didn't get to the hw anyway if changed) because the stashing device_flags (HAS_BD_STASHING|HAS_BUF_STASHING) were "accidentally" cleared during probe().

Removing the sysfs stubs for the Tx FIFOCFG and ATTRELI
(stashing) config registers, as these registers may only
be configured after a MAC reset, with the controller stopped
(i.e. during hw init, at probe() time).  The current sysfs
stubs allow on-the-fly updates of these registers (the locking
measures are useless and only add unecessary code).

Changing these registers is discouraged. Only the default values
will be used instead.

Moreover, the stashing (ATTRELI) configuration options were
effectively disabled (didn't get to the hw anyway if changed)
because the stashing device_flags (HAS_BD_STASHING|HAS_BUF_STASHING)
were "accidentally" cleared during probe().
