All,
I found this peculiar thing regarding the hashing in RSS. According to the
hashing algorithm, for a particular source and destination ip address and
port numbers, the packets should be always hashed to the same queue since
the hashing algorithm uses only a fixed secret key in addition to the

hhmm.. In the driver i am using, the secret key is fixed, its a constant 40
byte value.
In the RSS, after the hashing, rss looks at one indirection table (using
the hash value obtained from the hashing algo) which has the index of the
CPUs. Whichever the index that hash result in, that
hi,
further to our previous conversation, i would like to know in the igb e1000
for transmission of packets do they use a separate hash function? if so, any
clue which does that? or else do the igb e1000 driver transmits the packets
in the same queue where it had received the packet based on the
thanks a lot. that was of great help.
Also it would be great if you can tell me where i can study about the hash
function on both sides? is there any document on net?.

search for receive side scaling at microsoft.com for RSS.
for transmit, you'll just
