Subject: [PATCH] staging: fsl-dpaa2/mac: Request atomic context MC portals
|
|
|
|
The MAC driver may need to issue MC commands while in atomic
|
|
context (e.g. dpaa2_mac_get_stats can be called from a critical
|
|
section), so we need to use MC portals that don't sleep while
|
|
waiting for a command response to arrive.
