In case we have a layer 3 interface on top of a bridge (VLAN / FID RIF), then we should flood the following packet types to the router: * Broadcast: If DIP is the broadcast address of the interface, then we need to be able to get it to CPU by trapping it following route lookup. * Reserved IP multicast (224.0.0.X): Some control packets (e.g. OSPF) use this range and are trapped in the router block.

Instead of using sock_tx_timestamp, use skb_tx_timestamp to record software transmit timestamp of a packet. sock_tx_timestamp resets and overrides the tx_flags of the skb. The function is intended to be called from within the protocol layer when creating the skb, not from a device driver. This is inconsistent with other drivers and will cause issues for TCP. In TCP, we intend to sample the timestamps for the last byte for each sendmsg/sendpage. For that reason, tcp_sendmsg calls tcp_tx_timestamp only with the last skb that it generates. For example, if a 128KB message is split into two 64KB packets we want to sample the SND timestamp of the last packet. The current code in the tun driver, however, will result in sampling the SND timestamp for both packets. Also, when the last packet is split into smaller packets for retranmission (see tcp_fragment), the tun driver will record timestamps for all of the retransmitted packets and not only the last packet.

We currently enable interrupts before we enable NAPI. If an RX interrupt hits before we enabled NAPI then the NAPI callback is never called and we leave the hardware with RX interrupts disabled, which of course leads us to never handling received packets.

由 Zefir Kurtisi 提交于
The current scatter-gather logic in gianfar is flawed, since it does not consider the eTSEC's RxBD 'Data Length' field is context depening: for the last fragment it contains the full frame size, while fragments contain the fragment size, which equals the value written to register MRBLR. This causes data corruption as soon as the hardware starts to fragment receiving frames. As a result, the size of fragmented frames is increased by (nr_frags - 1) * MRBLR We first noticed this issue working with DSA, where an ICMP request sized 1472 bytes causes the scatter-gather logic to kick in. The full Ethernet frame (1518) gets increased by DSA (4), GMAC_FCB_LEN (8), and FSL_GIANFAR_DEV_HAS_TIMER (priv->padding=8) to a total of 1538 octets, which is fragmented by the hardware and reconstructed by the driver to a 3074 octet frame. This patch fixes the problem by adjusting the size of the last fragment. It was tested by setting MRBLR to different multiples of 64, proving correct scatter-gather operation on frames with up to 9000 octets in size.

The eTSEC register MRBLR defines the maximum space in the RX buffers and is set to 1536 by gianfar. This reasonably covers the common use case where the MTU is kept at default 1500. In that case, the largest Ethernet frame size of 1518 plus an optional GMAC_FCB_LEN of 8, and an additional padding of 8 to handle FSL_GIANFAR_DEV_HAS_TIMER totals to 1534 and nicely fit within the chosen MRBLR. Alas, if the eTSEC is attached to a DSA enabled switch, the (E)DSA header extension (4 or 8 bytes) causes every maximum sized frame to be fragmented by the hardware. This patch increases the maximum RX buffer size by 8 and rounds up to the next multiple of 64, which the hardware's defines as RX buffer granularity.

Driver uses netif_tx_queue_stopped() to make sure the xmit_more indication will be honored, but that only checks for DRV_XOFF. At the same time, it's possible that during transmission the DQL will close the transmission queue with STACK_XOFF indication. In re-configuration flows, when the threshold is relatively low, it's possible that the device has no pending tranmissions, and during tranmission the driver would miss doorbelling the HW. Since there are no pending transmission, there will never be a Tx completion [and thus the DQL would not remove the STACK_XOFF indication], eventually causing the Tx queue to timeout. While we're at it - also doorbell in case driver has to close the transmission queue on its own [although this one is less important - if the ring is full, we're bound to receive completion eventually, which means the doorbell would only be postponed and not indefinetly blocked].

Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers.

When packets enter the device they are classified to a priority group (PG) buffer based on their PCP value. After their egress port and traffic class are determined they are moved to the switch's shared buffer and await transmission, if: (Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres && Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres) || (Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min || Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min) Packets scheduled to transmission through CPU port (trapped to CPU) use traffic class 7, which has a zero maximum and minimum quotas. However, when such packets arrive from PG 0 they are admitted to the shared buffer as PG 0 has a non-zero minimum quota. Allow all packets to be trapped to the CPU - regardless of the PG they were classified to - by assigning a 10KB minimum quota for CPU port and TC7.
