packet loss on ixgbe using vlans and ipv6
Hi,
I have a Dell T710 with 4 X 10G ethernet interfaces (2 X Dual port Intel
82599 cards). It is running FreeBSD RELENG_8 last updated on July 13.
What I see is packet loss (0 - 40%) on IPv6 packets in vlans, when the
machine is not the originator of the packets.
Let me try to describe a little more. If a neigbouring machine ping6 it,
there will be packet loss. If it act as a router for ipv6,

still mbuf leak in 9.0 / 9.1?
Hi list,
since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the
system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands.
A clean shutdown isn't possible

Calculate NAs from known data: how to?
Hi
In a dataset I have length and age for cod. The age, however, is ony
given for 40-100% of the fish. What I need to do is to fill inn the NAs
in a correct way, so that age has a value for each length. This is to be
done for each sample seperately (there are 324 samples), meaning the NAs
for sampleno 1 shall be calculated from the known values from sampleno 1.
As for example length 55 cm

Lat Lon NetCDF subset
Hi,
I'm trying to read a subset of a netcdf file into R, but although I'm
relatively experienced using R, I'm still new to netCDF files, so this may
be a very simple/stupid question!
I've included an example of the type of file I'm looking at here.

Classifying values by interval
Greetings All!
As is often the case on this list, the answer may well
be under my nose but I can't see it!
I am looking for a "smart" way to do the following.

say with breaks at B = c(b1,b2,...,b11) covering the
range of X, i.e. bins numbered 1:10. The value x is in
bin i if B[i] < x <= B[i+1]

thread taskq / unp_gc() using 100% cpu and stalling unix socket IPC
Hi there
We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here:

Logic with regexps
Greetings,
The following question has come up in an off-list discussion.
Is it possible to construct a regular expression 'rex' out of
two given regular expressions 'rex1' and 'rex2', such that a
character string X matches 'rex' if and only if X matches 'rex1'
AND X does not match 'rex2'?
The desired end result can be achieved by logically combining

Subsetting a matrix
I'd welcome some comments or advice regarding the situation described
below.
The following illustrates what seems to me to be an inconsistency
in the behaviour of matrix subsetting:

> Z

efficiently diff two data frames
Dear all,
What is the quickest and most efficient way to diff two data frames,
so as to obtain a vector of indices (or logical) for rows/columns that
differ in the two data frames? For example,
> Xe <- head(mtcars)
> Xf <- head(mtcars)
> Xf[2:4,3:5] <- 55
> all.equal(Xe, Xf)

Re-order columns
Dear R'sians,
Would really appreciate if you could suggest a more efficient way to order
the columns of a dataset. The column names of the dataset contain indices
separated by a period. Following are examples of my code and the dataset.

lth <- length(grep("T",names(tg)))

questions from a 10GbE driver author
Hi,
I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow?
Also, can crossbow do things like steer outgoing packets to the

10Gbps network interfaces under KVM
Hi all,
Anyone knows if exists some plan to support Intel 10Gbps nics like ?for example 82575, 82576, 82580 or 82598EB Ethernet controllers under KVM for virtual guest like it does with e1000 driver?

Broadcom NetXtreme bcm5720 in the 9.1 beta
Team
I have a Dell PowerEdge R720xd, with the Broadcom NetXtreme bcm5720. I
found the following thread:
http://forums.freebsd.org/showthread.php?t=31769
I find I am unable to use the NIC's (there are 4 on the server). When we
put a cable into it we get a "watchdog timeout -- resetting" error, and
the machine will pause for 5 or so seconds. IP may or may not come up
randomly.

[PATCH 2/2] Add VMDq support to ixgbe
This patch adds experimental VMDq support (AKA Netchannel2 vmq) to the
ixgbe driver. This applies to the Netchannel2 tree, and should NOT be
applied to the "normal" development tree.
To enable VMDq functionality, load the driver with the command-line
parameter VMDQ=<num queues>, as in:
$ modprobe ixgbe VMDQ=8
You can then set up PV domains to use the device by modifying your VM

Guest still receive packet with vlan tag (SR-IOV transparent VLAN)
Hello everyone,
I'm having problem with SR-IOV transparent VLAN.
My host is Fedora 22 and my guest is: pfSense 2.3. The NIC is Intel 82576.
I'm using pfSense Packet Capture to check the packet and find that inbound
packet still have the vlan tag. The outbound packet seem fine because the
router can receive DHCP discover packet from the guest and then send DHCP

Hwo to disable the polling function of mac_srs
In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring"
to poll the hardware and crossbow will wakeup this thread to poll packets
from the hardware automatically. Does crossbow provide any method to disable
the polling mechanism, for example disabling the this kernel thread?
Thanks
