bnxt_en: Fix TX push operation on ARM64.

2016-09-24T08:09:26Z

[ Upstream commit 9d13744bb75078175ab49408f2abb980e4dbccc9 ] There is a code path where we are calling __iowrite64_copy() on an address that is not 64-bit aligned. This causes an exception on some architectures such as arm64. Fix that code path by using __iowrite32_copy(). Reported-by: JD Zheng Signed-off-by: Michael Chan Signed-off-by: David S.

net: bgmac: Fix infinite loop in bgmac_dma_tx_add()

2016-07-15T23:03:47Z

Nothing is decrementing the index "i" while we are cleaning up the fragments we could not successful transmit. Fixes: 9cde94506eacf ("bgmac: implement scatter/gather support") Reported-by: coverity (CID 1352048) Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

bnxt_en: initialize rc to zero to avoid returning garbage

2016-07-11T19:41:36Z

rc is not initialized so it can contain garbage if it is not set by the call to bnxt_read_sfp_module_eeprom_info. Ensure garbage is not returned by initializing rc to 0. Signed-off-by: Colin Ian King Acked-by: Michael Chan Signed-off-by: David S. Miller

net: bcmsysport: Device stats are unsigned long

2016-07-01T20:37:43Z

On 64bits kernels, device stats are 64bits wide, not 32bits. Fixes: 80105befdb4b ("net: systemport: add Broadcom SYSTEMPORT Ethernet MAC driver") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: bgmac: Remove superflous netif_carrier_on()

2016-06-28T08:22:17Z

bgmac_open() calls phy_start() to initialize the PHY state machine, which will set the interface's carrier state accordingly, no need to force that as this could be conflicting with the PHY state determined by PHYLIB.

net: bgmac: Start transmit queue in bgmac_open

2016-06-28T08:22:17Z

The driver does not start the transmit queue in bgmac_open(). If the queue was stopped prior to closing then re-opening the interface, we would never be able to wake-up again.

net: bgmac: Fix SOF bit checking

2016-06-28T08:22:17Z

We are checking for the Start of Frame bit in the ctl1 word, while this bit is set in the ctl0 word instead. Read the ctl0 word and update the check to verify that. Fixes: 9cde94506eac ("bgmac: implement scatter/gather support") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

bnxt_en: Simplify VLAN receive logic.

2016-06-07T23:02:03Z

Since both CTAG and STAG rx acceleration must be enabled together, we only need to check one feature flag (NETIF_F_HW_VLAN_CTAG_RX) before calling __vlan_hwaccel_put_tag(). Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: Enable and disable RX CTAG and RX STAG VLAN acceleration together.

2016-06-07T23:02:03Z

The hardware can only be set to strip or not strip both the VLAN CTAG and STAG. It cannot strip one and not strip the other. Add logic to bnxt_fix_features() to toggle both feature flags when the user is toggling one of them. Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: Fix tx push race condition.

2016-06-07T23:02:03Z

Set the is_push flag in the software BD before the tx data is pushed to the chip. It is possible to get the tx interrupt as soon as the tx data is pushed. The tx handler will not handle the event properly if the is_push flag is not set and it will crash. Signed-off-by: Michael Chan Signed-off-by: David S. Miller
