@JiangtianLi @tamilmani1989 @sharmasushant Could you please review? Thanks!

[JiangtianLi]

@saiyan86 It is hard to see the diff, possibly due to line ending? Can you adjust it?

[jackfrancis]

@JiangtianLi append ?w=1 to the end of the "Files changed" URL to remove whitespace changes.

@saiyan86 I've tagged this PR as do-not-merge. Please @ me when v1.0.4 is released and I'll move this effort forward. Thanks!

@JiangtianLi Sorry for the hassle, but the line ending seems to be fine with me.
I don't know why git treats all of them as difference.

[JiangtianLi]

@saiyan86 no problem. what link do you use to see the diff? Just curious what have changed recently. I didn't remember to append ?w=1 before.

[saiyan86]

@JiangtianLi I added a Set-AzureCNIConfig() function and calls it in Set-NetworkConfig
.

[JiangtianLi]

@saiyan86 Sorry I didn't mean what you have changed. I wonder if you can view the diff without ?w=1?

[saiyan86]

@JiangtianLi I can view the diff in my local VSCode. But for github, I have to add ?w=1.

[saiyan86]

@JiangtianLi @jackfrancis We just released Azure CNI v1.0.4. Could you please pull the binaries to acs-engine mirror and merge this PR? Thanks!!

[jackfrancis]

@saiyan86 I updated defaults.go to use the new version of Azure CNI. Let's run it through E2E.

[jackfrancis]

@saiyan86 Is there any additional Windows work that needs to happen for this PR, or should we assume successful E2E deployments indicate validation of the changes?

[PatrickLang]

If you can point me to a build (circleCI?) I can do a quick deploy
