Your compressed data for decompress OP doesn't include b-final bit in the last block.

May point to memory issue: cutting/garbage...

Hi,
I am new to dpdk development in general and have been trying some development on Nvidia BF2 but ran into some problems. I am using Compress device: mlx5_pci to do compression/decompression and it appears that compression is fine but when I try to decompress, I get the following error:

Decompress OP status is 3 and the debug_status is 273. Not sure how to interpret this error. Any help in deciphering this would be greatly appreciated. I apologize for missing any critical information.
