2016-06-16r8152: modify the check of the flag of PHY_RESET in set_speed functionhayeswang
In set_speed(), BMCR_RESET would be set when the flag of PHY_RESET is set. Use BMCR_RESET to replace testing the flag of PHY_RESET. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-06-14r8152: move the setting for the default speedhayeswang
Move calling set_speed() from open() to rtl_hw_phy_work_func_t(). Then, we would set the default speed only for first initialization or after resuming. Besides, the set_speed() could handle the flag of PHY_RESET which would be set in rtl_ops.hw_phy_cfg(). Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

2016-06-14r8152: move the settings of PHY to a work queuehayeswang
Move the settings of PHY to a work queue and schedule it after rtl_ops.init(). There are some reasons for this. First, the settings are only needed for the first time initialization or after the power down occurs. Second, the settings are independent with the others. Last, the settings may take more time than the others. Leave they in probe() or open() may delay the following flows. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

2016-05-17asix: Fix offset calculation in asix_rx_fixup() causing slow transmissionsJohn Stultz
In testing with HiKey, we found that since commit 3f30b158eba5 ("asix: On RX avoid creating bad Ethernet frames"), we're seeing lots of noise during network transfers: [ 239.027993] asix 1-1.1:1.0 eth0: asix_rx_fixup() Data Header synchronisation was lost, remaining 988 [ 239.037310] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x54ebb5ec, offset 4 [ 239.045519] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0xcdffe7a2, offset 4 [ 239.275044] asix 1-1.1:1.0 eth0: asix_rx_fixup() Data Header synchronisation was lost, remaining 988 [ 239.284355] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x1d36f59d, offset 4 [ 239.292541] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0xaef3c1e9, offset 4 [ 239.518996] asix 1-1.1:1.0 eth0: asix_rx_fixup() Data Header synchronisation was lost, remaining 988 [ 239.528300] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x2881912, offset 4 [ 239.536413] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x5638f7e2, offset 4 And network throughput ends up being pretty bursty and slow with a overall throughput of at best ~30kB/s (where as previously we got 1.1MB/s with the slower USB1.1 "full speed" host). We found the issue also was reproducible on a x86_64 system, using a "high-speed" USB2.0 port but the throughput did not measurably drop (possibly due to the scp transfer being cpu bound on my slow test hardware). After lots of debugging, I found the check added in the problematic commit seems to be calculating the offset incorrectly. In the normal case, in the main loop of the function, we do: (where offset is zero, or set to "offset += (copy_length + 1) & 0xfffe" in the previous loop) rx->header = get_unaligned_le32(skb->data + offset); offset += sizeof(u32); But the problematic patch calculates: offset = ((rx->remaining + 1) & 0xfffe) + sizeof(u32); rx->header = get_unaligned_le32(skb->data + offset); Adding some debug logic to check those offset calculation used to find rx->header, the one in problematic code is always too large by sizeof(u32). Thus, this patch removes the incorrect " + sizeof(u32)" addition in the problematic calculation, and resolves the issue. Cc: Dean Jenkins <Dean_Jenkins@mentor.com> Cc: "David B.

2016-05-01net/smscx5xx: use the device tree for mac addressArnd Bergmann
This takes the MAC address for smsc75xx/smsc95xx USB network devices from a the device tree. This is required to get a usable persistent address on the popular beagleboard, whose hardware designers accidentally forgot that an ethernet device really requires an a MAC address to be functional. The Raspberry Pi also ships smsc9514 without a serial EEPROM, stores the MAC address in ROM accessible via VC4 firmware. The smsc75xx and smsc95xx drivers are just two copies of the same code, so better fix both.

2016-04-14cdc_mbim: apply "NDP to end" quirk to all Huawei devicesBjørn Mork
We now have a positive report of another Huawei device needing this quirk: The ME906s-158 (12d1:15c1). This is an m.2 form factor modem with no obvious relationship to the E3372 (12d1:157d) we already have a quirk entry for. This is reason enough to believe the quirk might be necessary for any number of current and future Huawei devices. Applying the quirk to all Huawei devices, since it is crucial to any device affected by the firmware bug, while the impact on non-affected devices is negligible.

2016-02-18USB: cdc_subset: only build when one driver is enabledArnd Bergmann
This avoids a harmless randconfig warning I get when USB_NET_CDC_SUBSET is enabled, but all of the more specific drivers are not: drivers/net/usb/cdc_subset.c:241:2: #warning You need to configure some hardware for this driver The current behavior is clearly intentional, giving a warning when a user picks a configuration that won't do anything good. The only reason for even addressing this is that I'm getting close to eliminating all 'randconfig' warnings on ARM, and this came up a couple of times. My workaround is to not even build the module when none of the configurations are enable. Alternatively we could simply remove the #warning (nothing wrong for compile-testing), turn it into a runtime warning, or change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.
