2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-05-09net: smsc95xx: Correct free_pkt() implementationSimon Glass
On further review this returns the wrong packet length from the driver. It may not be noticed since protocols will take care of it. Fix it by subtracting the header length from the packet length returned. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-10-13net: smsc95xx: fix DM MAC address readingStephen Warren
eth-uclass.c expects DM-capable Ethernet adapters to implement ops-> read_rom_hwaddr(), or for some other mechanism to set pdata->enetaddr, or for the user to set environment variable $usbethaddr. Without any of these, it will refuse to initialize the device since no valid MAC address is known. Implement this function for the smsc95xx driver. With this feature implemented, there is no point smsc95xx_init_common() re-reading the MAC address from ROM, so ifdef out this code when DM_ETH is enabled. This allows (at least) the built-in Ethernet on the NVIDIA Harmony board to operate again.

2016-04-01smsc95xx: fix operation on 64-bit systemsStephen Warren
smsc95xx_read_reg() should calculate sizeof(*data) not sizeof(data) since data is a pointer, and the value pointed at is being transferred over USB, not the value of the pointer. This fixes operation of the driver in 64-bit builds, such as the Raspberry Pi 3.

2015-10-29smsc95xx: Use zero length packets when RX fifo is emptyStefan Brüns
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.

2015-10-28smsc95xx: Fetch whole burst with 1 URB, avoid framing errorsStefan Brüns
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.

2015-04-18net: cosmetic: Fix var naming net <-> eth driversJoe Hershberger
Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support.
