[dpdk-dev,v2,1/7] net/bnxt: fix size of tx ring in HW
Checks
Commit Message
During Tx ring allocation, the actual ring size configured in the HW
ends up being twice the number of txd parameter specified to the driver.
The power of 2 ring size wrongly adds a +1 while sending the ring
create command to the FW.
