H A Dif_athioctl.hdiff 123044 Fri Nov 28 23:23:59 MST 2003 sam o track API change for HAL v0.9.6.1
o fix race condition when processing rx descriptors: because we use
a self-linked descriptor at the end of the rx descriptor list to
avoid rx overruns (which can easily happen for 5212 parts that enable
PHY errors) we must carefully check that a descriptor is "done" by
looking ahead to the next descriptor before believing the done bit
in the current descriptor (this is all handled in the HAL since the
rx descriptor format is chip-specific so we need to pass in two
additional parameters--the physical address of the current descriptor
and the virtual address of the next descriptor in the list)
o check copyout return status for SIOCGATHSTATS ioctl
