Subject: [PATCH 5.15 040/913] bus: mhi: pci_generic: Add mru_default for Quectel EM1xx series

From: Yonglin Tan <yonglin.tan@...look.com>

commit 2413ffbf19a95cfcd7adf63135c5a9343a66d0a2 upstream.

For default mechanism, the driver uses default MRU 3500 if mru_default
is not initialized. The Qualcomm configured the MRU size to 32768 in the
WWAN device FW. So, we align the driver setting with Qualcomm FW setting.
