smsc95xx: Use zero length packets when RX fifo is empty

2015-10-29T19:05:46+00:00

Using NAKs on empty RX fifo for bulk in transfers is the right choice
for a interrupt driven model, but U-Boot uses polling and expects an
immediate answer if there is no incoming packet. Using ZLP Bulk In Response
(BIR) mode avoids unexpected timeouts in the host controller driver.

As ZLP mode is reset default, there is no need to set it.

smsc95xx: Fetch whole burst with 1 URB, avoid framing errors

2015-10-28T19:59:28+00:00

smsc95xx_recv() does not reassemble bursts spread over multiple URBs.
If there is a lot of broadcast traffic, the fifo will fill up to the
burst cap limit. Lowering the burst cap to the URB size ensures no packet
spans multiple urbs.
Caveat, lower limit for working burst cap is 5/33 HS/FS packets.

dm: Rename dev_get_parentdata() to dev_get_parent_priv()

2015-10-23T15:42:28+00:00

The current name is inconsistent with other driver model data access
functions. Rename it and fix up all users.

Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20+00:00

Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

net: smsc95xx: Add driver-model support

2015-08-06T13:44:28+00:00

Add support for driver model, so that CONFIG_DM_ETH can be defined and used
with this driver.

net: smsc95xx: Prepare for conversion to driver model

2015-08-06T13:44:27+00:00

At present struct eth_device is passed around all over the place. This does
not exist with driver model. Add explicit arguments instead, so that with
driver model we can pass the correct things.

net: smsc95xx: Correct the error numbers

2015-08-06T13:40:45+00:00

Instead of returning -1 on error, we should use a proper error number. Fix
the code to conform to this.

net: smsc95xx: Rename AX_RX_URB_SIZE to RX_URB_SIZE

2015-08-06T13:31:37+00:00

The AX_ prefix comes from the Asix driver. Since this is not that, we should
avoid this confusing prefix.
