[PATCH v1] drivers:atlx:Use max macro
Posted by Yang Ruibin 1 year, 5 months ago
Instead of using the max() implementation of
the ternary operator, use real macros.

Sorry, please ignore this patch.
Because the corresponding header file is not included, there may be 
compilation errors.

Hi Yang Ruibin,

Thanks for your patch.

Some feedback from a process point of view, for future reference.

1. Please do not top-post in emails to Kernel mailing lists.

2. As a Networking patch, that is not a bug fix, it should
   be explicitly targeted at net-next.

   Subject: [PATCH net-next] ...

3. Looking at git history, it looks like 'net: atheros: ' would be an
   appropriate prefix for this patch.

   Subject: [PATCH net-next] net: atheros: ...

Please consider reading
https://docs.kernel.org/process/maintainer-netdev.html

And please, if you do post a new version, allow 24h to pass since the you
posted this version (as described in the link above).

Networking code still prefers lines to be 80 colimns wide or less.
In this case, I would suggest:

	adapter->hw.fc_rxd_lo = max(ATL2_MIN_RXD_COUNT / 8,
				    adapter->rxd_ring_size / 12);
