Based on a patch from Michael Ellerman, clean up a significant portion of the transmit path. There was a lot of duplication here. Even worse, we were always checksumming tx packets and ignoring the skb->ip_summed field. Also remove NETIF_F_FRAGLIST from dev->features, I'm not sure why it was enabled.

The ehea adapter has a mode where it will avoid partial cacheline DMA writes on receive by always padding packets to fall on a cacheline boundary. Unfortunately we currently aren't allocating enough space for a full ethernet MTU packet to be rounded up, so this optimisation doesn't hit. It's unfortunate that the next largest packet size exposed by the hypervisor interface is 2kB, meaning our skb allocation comes out of a 4kB SLAB. However the performance increase due to this optimisation is quite large and my TCP stream numbers increase from 900MB to 1000MB/sec.

The ehea driver had some multiqueue support but was missing the last few years of networking stack improvements: - Use skb_record_rx_queue to record which queue an skb came in on. - Remove the driver specific netif_queue lock and use the networking stack transmit lock instead. - Remove the driver specific transmit queue hashing and use skb_get_queue_mapping instead. - Use netif_tx_{start|stop|wake}_queue where appropriate. We can also remove pr->queue_stopped and just check the queue status directly. - Print all 16 queues in the ethtool stats. We now enable multiqueue by default since it is a clear win on all my testing so far. v3: [cascardo] fixed use_mcs parameter description [cascardo] set ehea_ethtool_stats_keys as const Signed-off-by: NAnton Blanchard <anton@samba.org> Signed-off-by: NThadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Signed-off-by: NDavid S.

Commit 67fd4fcb (e1000e: convert to stats64) added the ability to update statistics more accurately and on-demand through the net_device_ops .ndo_get_stats64 hook, but introduced a locking bug on 82577/8/9 when linked at half-duplex (seen on kernels with CONFIG_DEBUG_ATOMIC_SLEEP=y and CONFIG_PROVE_LOCKING=y). The commit introduced code paths that caused a mutex to be locked in atomic contexts, e.g. an rcu_read_lock is held when irqbalance reads the stats from /sys/class/net/ethX/statistics causing the mutex to be locked to read the Phy half-duplex statistics registers. The mutex was originally introduced to prevent concurrent accesses of resources (the NVM and Phy) shared by the driver, firmware and hardware a few years back when there was an issue with the NVM getting corrupted. It was later split into two mutexes - one for the NVM and one for the Phy when it was determined the NVM, unlike the Phy, should not be protected by the software/firmware/hardware semaphore (arbitration of which is done in part with the SWFLAG bit in the EXTCNF_CTRL register). This latter semaphore should be sufficient to prevent resource contention of the Phy in the driver (i.e. the mutex for Phy accesses is not needed), but to be sure the mutex is replaced with an atomic bit flag which will warn if any contention is possible. Also add additional debug output to help determine when the sw/fw/hw semaphore is owned by the firmware or hardware.

Currently Tx IQ calibration is enabled by default for all AR9003 chips. But for AR9480, the calibration status should be read from chip after processing ini. And also the carrier leak calibration status is checked during init cal. As the init_cal is being called for fast channel change too, the tx_cl status only be read after full reset.

In order to reduce the overall scan time, fast channel change should be implemented properly. This patch adds fast channel change support across band switch or channel mode switch instead of doing full chip reset. During the fastcc, tx iqcal measurements are preserved and will be reloaded after successful the channel change. This patch also addressed fast channel issue where the STA can not see APs in higher than operating channel on 5GHz band after the association.
