[ Upstream commit 98998ffe5216c7fa2c0225bb5b049ca5cdf8d195 ]
Due to recent advances in the firmware for Broadcom's gen p5 series of
adaptors the driver code to report hardware counters has been broken
w.r.t. roce devices.
The new firmware command expects dma length to be specified during stat
dma buffer allocation.
Fixes: 2792b5b95ed5 ("bnxt_en: Update firmware interface spec. to 1.10.0.89.")
