Pointer cmpl used to iterate through completion entries is updated at the beginning of while loop as well as at the end. The update at the end of the loop is useless. Signed-off-by:

Patch converts kzalloc->copy_from_user sequence to memdup_user. There is also one useless assignment of NULL to bnad->regdata as it is followed by assignment of kzalloc output. Signed-off-by:

TX_E_PRIO_CHANGE event is never sent for bna_tx so it doesn't need to be handled. After this change bna_tx->flags cannot contain BNA_TX_F_PRIO_CHANGED flag and it can be also eliminated. Signed-off-by:

The bna_rx_config struct member paused can be removed as it is never written and as it cannot have non-zero value the bna_rxf struct member flags also cannot have BNA_RXF_F_PAUSED value and is always zero. So the flags member can be removed as well as bna_rxf_flags enum and the code-paths that needs to have non-zero bna_rxf->flags. This clean-up makes bna_rxf_sm_paused state unsed and can be also removed. Signed-off-by: -

RXF_E_PAUSE & RXF_E_RESUME events are never sent for bna_rxf object so they needn't to be handled. The bna_rxf's state bna_rxf_sm_fltr_clr_wait and function bna_rxf_fltr_clear are unused after this so remove them also. Signed-off-by:

The patch converts mac_t type to widely used 'u8 [ETH_ALEN]'. Signed-off-by:

Ivan Vecera authored
Parameters of all ether_addr_copy instances were checked for proper alignment. Alignment of bnad_bcast_addr is forced to 2 as the implicit alignment is 1. I have also renamed address parameter of bnad_set_mac_address() to addr. The name mac_addr was a little bit confusing as the real parameter is struct sockaddr *. v2: added __aligned directive to bnad_bcast_addr, renamed parameter of bnad_set_mac_address() (thx joe@perches.com) Signed-off-by: -

Each transport object, namely TIR and TIS, must have a transport domain number (TDN) identifier. The driver wrongly assumed that it is OK to use TDN=0 without explicit TDN allocation from the device. The TDN will also be used for isolating different processes once user mode Ethernet will be supported. Signed-off-by:

When NETIF_F_SG is set, each send WQE may have a different size since each skb can have different number of fragments as of LSO header etc. This implies that a given WQE may wrap around the send queue, i.e begin at its end and continue at its start. While it is legal by the device spec, we preferred a solution that avoids it - when building of current WQE is done, if the next WQE may wrap around the send queue, fill the send queue with NOPs WQEs till its end, so that the next WQE will begin at send queue start. NOP WQE for itself cannot wrap around the send queue since it is of minimal size - 64 bytes, and all send WQEs are a multiple of that size. Signed-off-by:

We need to resolve a HW configuration issue for enabling HW CVLAN insertion. Meanwhile, no need to implement the VLAN insertion in the driver, rather use the generic kernel VLAN insertion method. Signed-off-by:

Previously we configured HW MTU to be netdev->mtu, actually we need to configure netdev->mtu + (ETH_HLEN + VLAN_HLEN + ETH_FCS_LEN). Also, query MTU can not fail, hence make the relevant helper a void functionm, add mlx5e_set_dev_port_mtu, helper function to handle MTU setting. Signed-off-by:

When the DEBUG preprocessor macro is defined the ps3_gelic_net driver build fails due to an undeclared routine gelic_descr_get_status(). This problem was introduced during the code cleanup of commit 6b0c21ce (net: Fix p3_gelic_net sparse warnings), which re-arranged the ordering of some of the gelic routines. This change just moves the gelic_descr_get_status() routine up in the ps3_gelic_net.c source file. There is no functional change. Fixes build errors like these: drivers/net/ethernet/toshiba/ps3_gelic_net.c: error: implicit declaration of function gelic_descr_get_status Signed-off-by:

Florian Fainelli says: ==================== net: broadcom MDIO support for broken turn-around These two patches update the GENET and UniMAC MDIO controllers to deal with PHYs that are known to have a broken turn-around bug (e.g: BCM53125 and others) This utilizes the infrastructure that code recently added to do that in 'net-next'. Note that the changes look nearly identical and I will try to address the MDIO code duplication between GENET and UniMAC in a future patch series. Changes in v2: - remove brcmphy.h include in mdio-bcm-unimac.c - use the same comment as with GENET's MDIO read function ==================== Signed-off-by: -
Florian Fainelli authored
Some Ethernet PHYs/switches such as Broadcom's BCM53125 have a hardware bug which makes them not release the MDIO line during turn-around time. This gets flagged by the UniMAC MDIO controller as a read failure, and we fail the read transaction. Check the MDIO bus phy_ignore_ta_mask bitmask for the PHY we are reading from and if it is listed in this bitmask, ignore the read failure and proceed with returning the data we read out of the controller.

Add PHY IDs for Davicom DM9161B and DM9161C variants. Tested with a DM9161C on a custom Atmel-based SAM9X25 board in RMII mode. The DM9161B uses the same model id with just the LSB bit of the version id changing (which is masked out). For all intents and purposes they're the same as the DM9161A with an added GPSI mode and better fabrication process. Signed-off-by:

Ethernet AVB device includes the gPTP timer, so we can implement a PTP clock driver. We're doing that in a separate file, with the main Ethernet driver calling the PTP driver's [de]initialization and interrupt handler functions. Unfortunately, the clock seems tightly coupled with the AVB-DMAC, so when that one leaves the operation mode, we have to unregister the PTP clock... :-( Based on the original patches by Masaru Nagai.

Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically compatible with SuperH Gigabit Ethernet E-MAC. Ethernet AVB has a dedicated direct memory access controller (AVB-DMAC) that is a new design compared to the SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE 802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real- time transfer, and the IEEE 802.1Qat stream reservation protocol. The driver only supports device tree probing, so the binding document is included in this patch. Based on the original patches by Mitsuhiro Kimura. Signed-off-by:

CAIA Delay-Gradient (CDG) is a TCP congestion control that modifies the TCP sender in order to [1]: o Use the delay gradient as a congestion signal. o Back off with an average probability that is independent of the RTT. o Coexist with flows that use loss-based congestion control, i.e., flows that are unresponsive to the delay signal. o Tolerate packet loss unrelated to congestion. (Disabled by default.) Its FreeBSD implementation was presented for the ICCRG in July 2012; slides are available at http://www.ietf.org/proceedings/84/iccrg.html Running the experiment scenarios in [1] suggests that our implementation achieves more goodput compared with FreeBSD 10.0 senders, although it also causes more queueing delay for a given backoff factor. The loss tolerance heuristic is disabled by default due to safety concerns for its use in the Internet [2, p. 45-46]. We use a variant of the Hybrid Slow start algorithm in tcp_cubic to reduce the probability of slow start overshoot. [1] D.A. Hayes and G. Armitage.
