net: usbnet: support 64bit stats

2017-04-04T02:09:40+00:00

Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms.

net: usb: mcs7830: use new api ethtool_{get|set}_link_ksettings

2017-03-21T23:04:00+00:00

The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes Tested-by: poma Signed-off-by: David S. Miller

drivers/net: get rid of unnecessary initializations in .get_drvinfo()

2015-10-16T07:24:10+00:00

Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len, eedump_len & regdump_len fields in their .get_drvinfo() ethtool op. It's not necessary as these fields is filled in ethtool_get_drvinfo(). v2: removed unused variable v3: removed another unused variable Signed-off-by: Ivan Vecera Signed-off-by: David S. Miller

usbnet: remove generic hard_header_len check

2014-02-17T19:35:46+00:00

This patch removes a generic hard_header_len check from the usbnet module that is causing dropped packages under certain circumstances for devices that send rx packets that cross urb boundaries. One example is the AX88772B which occasionally send rx packets that cross urb boundaries where the remaining partial packet is sent with no hardware header. When the buffer with a partial packet is of less number of octets than the value of hard_header_len the buffer is discarded by the usbnet module. With AX88772B this can be reproduced by using ping with a packet size between 1965-1976. The bug has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=29082 This patch introduces the following changes: - Removes the generic hard_header_len check in the rx_complete function in the usbnet module. - Introduces a ETH_HLEN check for skbs that are not cloned from within a rx_fixup callback. - For safety a hard_header_len check is added to each rx_fixup callback function that could be affected by this change. These extra checks could possibly be removed by someone who has the hardware to test. - Removes a call to dev_kfree_skb_any() and instead utilizes the dev->done list to queue skbs for cleanup. The changes place full responsibility on the rx_fixup callback functions that clone skbs to only pass valid skbs to the usbnet_skb_return function.

drivers/net: delete non-required instances of include

2014-01-16T19:53:26+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. This covers everything under drivers/net except for wireless, which has been submitted separately. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

usbnet: mcs7830: rework link state detection

2013-12-31T21:53:51+00:00

Even with the quirks in commit dabdaf0c (mcs7830: Fix link state detection) there are still spurious link-down events for some chips where the false link-down events count go over a few hundreds. This patch takes a more conservative approach and only looks at link-down events where the link-down state is not combined with other states (e.g. half/full speed, pending frames in SRAM or TX status information valid). In all other cases we assume the link is up. Tested on MCS7830CV-DA (USB ID 9710:7830). Cc: Ondrej Zary Cc: Michael Leun Cc: Ming Lei Signed-off-by: Octavian Purdila Signed-off-by: David S. Miller

usb: Fix FSF address in file headers

2013-12-06T17:37:55+00:00

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

usbnet: mcs7830: don't reset link

2013-04-11T19:57:16+00:00

The driver doesn't implement link_reset() callback, so it needn't to send link reset event. Signed-off-by: Ming Lei Signed-off-by: David S. Miller
