Subject: [PATCH 1/2] net: airoha: read default PSE reserved pages value before
|
|
updating
|
|
|
|
Store the default value for the number of PSE reserved pages in orig_val
|
|
at the beginning of airoha_fe_set_pse_oq_rsv routine, before updating it
|
|
with airoha_fe_set_pse_queue_rsv_pages().
|
|
Introduce airoha_fe_get_pse_all_rsv utility routine.
|
|
|
|
Introduced by commit 23020f049327 ("net: airoha: Introduce ethernet support
|
|
for EN7581 SoC")
