[PATCH net v2 2/2] bnge: remove unsupported backing store type

Vikas Gupta
2026-04-15T15:16:43Z

The backing store type, BNGE_CTX_MRAV, is not applicable in Thor Ultra
devices. Remove it from the backing store configuration, as the firmware
will not populate entities in this backing store type, due to which the
driver load fails.

Fixes: 29c5b358f385 ("bng_en: Add backing store support")
