Subject: [PATCH 08/12] net: airoha: ppe: Flush PPE SRAM table during PPE setup
|
|
|
|
Rely on airoha_ppe_foe_commit_sram_entry routine to flush SRAM PPE table
|
|
entries. This patch allow moving PPE SRAM flush during PPE setup and
|
|
avoid dumping uninitialized values via the debugfs if no entries are
|
|
offloaded yet.
