The canonical code to read iov[] from userspace is currently:
struct iovec iovstack[UIO_FASTIOV];
struct iovec *iov;
...
iov = iovstack;
rc = import_iovec(..., UIO_FASTIOV, &iov, &iter);
if (rc < 0)
return rc;
...
kfr
This lets the compiler inline it into import_iovec() generating
much better code.

Hi all,
this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs
with a separate new dma_alloc_pages API, which is available on all

The au1000-eth driver contains none of the manual cache synchronization
required for using DMA_ATTR_NON_CONSISTENT. From what I can tell it

I suspect it has been buggy on the non-coherent platforms all along.

mscc_ocelot_probe() is already pretty large and hard to follow. So move
the code for parsing ports in a separate function.
This makes it easier for the next patch to just call
mscc_ocelot_release_ports from the error path of mscc_ocelot_init_ports.

This is a series of 7 assorted patches for "net", on the drivers for the
VSC7514 MIPS switch (Ocelot-1), the VSC9953 PowerPC (Seville), and a few
more that are common to all supported devices since they are in the
common library portion.

The TX-timestampable skb is added late to the ocelot_port->tx_skbs. It
is in a race with the TX timestamp IRQ, which checks that queue trying
to match the timestamp with the skb by the ts_id. The skb should be
added to the queue before the IRQ can fire.
Fixes: 4e3b0468e6d7
The bpf_skc_to_* type casting helpers are available to
BPF_PROG_TYPE_TRACING. The traced PTR_TO_BTF_ID may be NULL.
For example, the skb->sk may be NULL. Thus, these casting helpers
need to check "!sk" also and this patch fixes them.
Fixes: 0d4fad3e57df ("bpf: Add bpf_skc_to_udp6_sock() helper")
Hello
As per patch https://lore.kernel.org/patchwork/patch/1300241/ the link
modes for 100base FX full and half duplex modes did not exist. Adding these
link modes to the core and ethtool allow devices like the DP83822, DP83869 and
Broadcomm PHYs to properly advertise the correct mode for Fiber 1

Add Queue Pair (QP) error notification to the user e.g. security violation,
too many retransmissions, invalid QP etc.
Whenever a QP caused an error, the firmware will send an event to the
driver which will push the error as an error entry to the Completion Queue
(if exists)

Finally, enable the NIC engines. Initialize the NIC ports mask variable
with full mask so all ports will be initialized.
Call the NIC init/fini from the common code.

Thanks! In all fairness, Jakub reviewed this in v1 too but I made enough

Basic NIC driver which handles Ethernet packet of several types like IPv4,
IPv6, LLDP, VLAN and ARP.
The NIC HW is composed of 5 NIC macros, in each macro 2 NIC engines of
100GbE each. Each engine exposes a single port of 100GbE, so in total we
have 10 ports per GAUDI devic
