ether_vlanencap

Hi, I'm trying to insert vlan tag into the packet using ether_vlanencap but the packet is getting corrupted in the mbuf and m_len is also showing a wrong length. Am I doing something wrong here? Can I directly pass mbuf pointer and vlan tag to this api for inserting the vlan tag? /Venkat

PCI BAR mmap

Hi, How to mmap PCI BARs from userland in freebsd? In Linux the PCI BAR appears as a file in the sysfs file system. How can I access PCI BAR as a file in freebsd to mmap it? /Venkat ___ freebsd-questions@freebsd.org mailing list

Freebsd build problem

Hi, I'm unable to compile the kernel code (for that matter any kernel module also). The following is the error. My guess is that it is trying to compile the code for x86 instead of amd64 as you can a symbolic link create for x86 includes. Please suggest the change to be done inorder to compile it

MSI-X limitation in freebsd 8.2

Hi, MSI-x supports upto 2048 vectors but what I see in freebsd 8.2 is that when I use more than ~30 vectors, system becomes dead slow. Is there a limitation on number of msi vectors that can be used in 8.2? ___ freebsd-questions@freebsd.org mailing list

Re: LRO support for IPv6

Folks, Can somebody please explain me why tcp checsum calculation is mandated in the freebsd network stack (tcp_input---in6_cksum) albeit the card supports it? Probably Steve is the right person who can answer this. /Venkat On Wed, May 23, 2012 at 11:27 AM, Venkat Duvvuru venkatduvvuru

LRO support for IPv6

Folks, Could somebody please tell about the base Freebsd version which has LRO support for IPv6? I'm using 9.0-RELEASE and I see that tcp_lro_rx is failing. Please confirm. /Venkat ___ freebsd-questions@freebsd.org mailing list

Re: LRO support for IPv6

Thanks for the response. I observed that there is a significant performance drop in case of IPv6 on the rx side. While I'm able to hit line rate ~9.5 Gbps on a 10gb NIC for IPv4..I could only get ~6 Gbps on the rx front for IPv6...However tx for IPv6 is on par with IPv4 hitting almost line rates.

Extend Error Handling

Linux has a feature called EEH (extended error handling) which is introduced to handle PCI errors gracefully. Is EEH supported in freebsd as well? I looked into the documentation of freebsd and briefly looked into the freebsd source tree as well but couldn't find anything like that. Please

IPv6 flow id hash calculation

Folks, This question is related to the hash calculation done as part of selecting the transmit queue for IPv6 traffic. I observed that no matter how many queues you use in the driver, the tx traffic is always coming on queue 0. Did anybody else observed this behaviour? and is that how it is in
