Comment (by Przemyslaw Bruski):
Hi,
I've noticed a problem with changeset r3548 that occurs when fast frames
are enabled.
The changeset assumes equivalence between {{{ds->ds_link}}} and
{{{bf->bf_desc->ds_link}}}, however, the descriptor address for the last
fast frame is in fact zeroed in this code section:
{{{
ds->ds_link = (skbtmp->next == NULL) ?
0 : bf->bf_daddr + (sizeof(*ds) * (i +
2));
}}}
This means that for the last fast frame the assumed equivalence does not
exist.
Whenever a fast frame is processed, the transmission on card is for some
time. Temporary solution - disable FF or back out r3458.
bye,
Przemek
