Code includes barrier() followed by writel(). writel() already has a
barrier on some architectures like arm64.
This ends up CPU observing two barriers back to back before executing the
register write.
Create a new wrapper function with relaxed write operator. Use the new
wrapper when a write is following a barrier().
Since code already has an explicit barrier call, changing writel() to
writel_relaxed() and adding mmiowb() for ordering protection.

net: ena: add detection and recovery mechanism for handling missed/misrouted MSI-X
A mechanism for detection of stuck Rx/Tx rings due to missed or
misrouted interrupts.
Check if there are unhandled completion descriptors before the first
MSI-X interrupt arrived.
The check is per queue and per interrupt vector.
Once such condition is detected, driver and device reset is scheduled.

UBUNTU: [Config] update Build-Depends: transfig to fig2dev
Some time back transfig became a transitional package to fig2dev.
In cosmic this transitional has now been deprecated. As we are still
copying kernels forward we need to fix this dependency in bionic.
This transition actually occured back in artful, we just missed it.
Switch our build dependency to the "new" fig2dev package.
