net: systemport: Fix missing Wake-on-LAN interrupt for SYSTEMPORT Lite

2017-06-14T13:07:33+00:00

[ Upstream commit d31353cd753c443ace5723d6878a39f393a0c136 ] On SYSTEMPORT Lite, since we have the main interrupt source in the first cell, the second cell is the Wake-on-LAN interrupt, yet the code was not properly updated to fetch the second cell, and instead looked at the third and non-existing cell for Wake-on-LAN.

bnx2x: Fix Multi-Cos

2017-06-14T13:07:32+00:00

[ Upstream commit 3968d38917eb9bd0cd391265f6c9c538d9b33ffa ] Apparently multi-cos isn't working for bnx2x quite some time - driver implements ndo_select_queue() to allow queue-selection for FCoE, but the regular L2 flow would cause it to modulo the fallback's result by the number of queues. The fallback would return a queue matching the needed tc [via __skb_tx_hash()], but since the modulo is by the number of TSS queues where number of TCs is not accounted, transmission would always be done by a queue configured into using TC0.

bnxt_en: Fix NULL pointer dereference in reopen failure path

2017-03-29T21:05:33+00:00

Net device reset can fail when the h/w or f/w is in a bad state. Subsequent netdevice open fails in bnxt_hwrm_stat_ctx_alloc(). The cleanup invokes bnxt_hwrm_resource_free() which inturn calls bnxt_disable_int(). In this routine, the code segment if (ring->fw_ring_id != INVALID_HW_RING_ID) BNXT_CP_DB(cpr->cp_doorbell, cpr->cp_raw_cons); results in NULL pointer dereference as cpr->cp_doorbell is not yet initialized, and fw_ring_id is zero. The fix is to initialize cpr fw_ring_id to INVALID_HW_RING_ID before bnxt_init_chip() is invoked. Signed-off-by: Sankar Patchineelam Signed-off-by: Michael Chan Signed-off-by: David S. Miller

net: bcmgenet: remove bcmgenet_internal_phy_setup()

2017-03-22T19:47:26+00:00

Commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset") removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and bcmgenet_internal_phy_setup() functions. In so doing it broke the reset of the internal PHY devices used by the GENETv1-GENETv3 which required this reset before the UniMAC was enabled. It also broke the internal GPHY devices used by the GENETv4 because the config_init that installed the AFE workaround was no longer occurring after the reset of the GPHY performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). In addition the code in bcmgenet_internal_phy_setup() related to the "enable APD" comment goes with the bcmgenet_mii_reset() so it should have also been removed. Commit bd4060a6108b ("net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the bcmgenet_power_up() function, but failed to remove it from the bcmgenet_internal_phy_setup() function. Had it done so, the bcmgenet_internal_phy_setup() function would have been empty and could have been removed at that time. Commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") was submitted to correct the functional problems introduced by commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset"). It was included in v4.4 and made available on 4.3-stable. Unfortunately, it didn't fully revert the commit because this bcmgenet_mii_reset() doesn't apply the soft reset to the internal GPHY used by GENETv4 like the previous one did. This prevents the restoration of the AFE work- arounds for internal GPHY devices after the bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). This commit takes the alternate approach of removing the unnecessary bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3 so that when bcmgenet_mii_reset() was restored it should have only gone into bcmgenet_power_up(). This will avoid the problems while also removing the redundancy (and hopefully some of the confusion).

net: bcmgenet: Do not suspend PHY if Wake-on-LAN is enabled

net: bcmgenet: decouple flow control from bcmgenet_tx_reclaim

2017-03-10T02:39:01+00:00

The bcmgenet_tx_reclaim() function is used to reclaim transmit resources in different places within the driver. Most of them should not affect the state of the transmit flow control. This commit relocates the logic for waking tx queues based on freed resources to the napi polling function where it is more appropriate.
