[dpdk-stable] [PATCH v3 1/7] net/bnxt: fix size of tx ring in HW

[Ajit Khaparde]

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.
