This pushes qed [and as result, all qed* drivers] into using 8.20.0.0 firmware. The changes are mostly contained in qed with minor changes to qedi due to some HSI changes. Content-wise, the firmware contains fixes to various issues exposed since the release of the previous firmware, including: - Corrects iSCSI fast retransmit when data digest is enabled. - Stop draining packets when receiving several consecutive PFCs. - Prevent possible assertion when consecutively opening/closing many connections. - Prevent possible assertion due to too long BDQ fetch time. In addition, the new firmware would allow us to later add iWARP support in qed and qedr. Changes from previous version ----------------------------- - V2: Fix warning in qed_debug.c Signed-off-by:

skbs in (re)transmit queue no longer have a copy of jiffies at the time of the transmit : skb->skb_mstamp is now in usec unit, with no correlation to tcp_jiffies32. We have to convert rto from jiffies to usec, compute a time difference in usec, then convert the delta to HZ units.

Cygnus is a small family of SoCs, of which we currently have devicetree for BCM11360 and BCM58300. The 11360's B53 is mostly the same as 58xx, just requiring a tiny bit of setup that was previously missing. Signed-off-by:

Vivien Didelot says: ==================== net: dsa: headers cleanup The DSA core files share a common private header file. Include the DSA public header there instead of independently in each core source file. DSA core and its drivers use switchdev, thus include switchdev.h in the public DSA header. This allows us to get rid of the forward declaration and use typedef defined by switchdev. ==================== Signed-off-by: -

This adds support for hdlc-bus mode to the fsl_ucc_hdlc driver. This can be enabled with the "fsl,hdlc-bus" property in the DTS node of the corresponding ucc. This aligns the configuration of the UPSMR and GUMR registers to what is done in our ucc_hdlc driver (that only support hdlc-bus mode) and with the QuickEngine's documentation for hdlc-bus mode. GUMR/SYNL is set to AUTO for the busmode as in this case the CD signal is ignored. The brkpt_support is enabled to set the HBM1 bit in the CMXUCR register to configure an open-drain connected HDLC bus. Signed-off-by:

We can't assume that we are always in loopback mode if rx and tx clock have the same clock source. If we want to use HDLC busmode we also have the same clock source but we are not in loopback mode. So move the setting of the baudrate generator after the check for property for the loopback mode. Signed-off-by:

Jason Wang says: ==================== vhost_net rx batch dequeuing This series tries to implement rx batching for vhost-net. This is done by batching the dequeuing from skb_array which was exported by underlayer socket and pass the sbk back through msg_control to finish userspace copying. This is also the requirement for more batching implemention on rx path. Tests shows at most 7.56% improvment bon rx pps on top of batch zeroing and no obvious changes for TCP_STREAM/TCP_RR result. Please review. Thanks Changes from V4: - drop batch zeroing patch - renew the performance numbers - move skb pointer array out of vhost_net structure Changes from V3: - add batch zeroing patch to fix the build warnings Changes from V2: - rebase to net-next HEAD - use unconsume helpers to put skb back on releasing - introduce and use vhost_net internal buffer helpers - renew performance numbers on top of batch zeroing Changes from V1: - switch to use for() in __ptr_ring_consume_batched() - rename peek_head_len_batched() to fetch_skbs() - use skb_array_consume_batched() instead of skb_array_consume_batched_bh() since no consumer run in bh - drop the lockless peeking patch since skb_array could be resized, so it's not safe to call lockless one ==================== Acked-by:

We used to dequeue one skb during recvmsg() from skb_array, this could be inefficient because of the bad cache utilization and spinlock touching for each packet. This patch tries to batch them by calling batch dequeuing helpers explicitly on the exported skb array and pass the skb back through msg_control for underlayer socket to finish the userspace copying. Batch dequeuing is also the requirement for more batching improvement on receive path. Tests were done by pktgen on tap with XDP1 in guest.

Applications that consume a batch of entries in one go can benefit from ability to return some of them back into the ring. Add an API for that - assuming there's space. If there's no space naturally can't do this and have to drop entries, but this implies ring is full so we'd likely drop some anyway. Signed-off-by:

To avoid possible ECC/parity checksum errors when reading an uninitialized buffer, the entire Message RAM is initialized when probing the driver. This initialization is done in the same function reading the Device Tree properties. This patch moves the RAM initialization to a separate function so it can be called separately from device initialization from Device Tree. Signed-off-by:
