Hi Alex,
I have a quick question about the ixgbe parameter FdirPballoc in relation to
using flow director filters and the size of the 8 packet buffers.
FdirPballoc:Flow Director packet buffer allocation level:
1 = 8k hash filters or 2k perfect filters - hw buffer reduced to 448Kb
2 = 16k hash filters or 4k perfect filters - hw buffer reduced to 384Kb
3 = 32k hash filters or 8k perfect filters - hw buffer reduced to 256Kb
The hardware buffers are 512Kb in size but they if using flow director the
size of the buffer is diminished based on the settings for FdirPballoc.
So for perfect filters is it a case if I set the value to 1 for FdirPballoc,
I can supply up to 2,000 individual filter configurations via ethtool? Does
wildcarding impact this?
Regards
Jonathan
