| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A previous patch (net: asix: fix operation without eeprom) added a two-byte shift to the packet buffer when receiving a packet on the AX88772B. This shift was not included when the driver was updated to work with DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter was not functioning correctly (EHCI timeouts). This patch brings the two-byte shift to the DriverModel implementation of ops->recv (asix_eth_recv).

This hang issue does not happen on the NXP U-Boot version. After comparing the SPL DDR initialization against the DCD table from NXP U-Boot, the key difference that causes the hang is the MDREF register setting: DATA 4 0x021B0020 0x00000800 ,which means: REF_SEL = 0 --> Periodic refresh cycle: 64kHz REFR = 1 ---> Refresh Rate - 2 refreshes So adjust the MDREF initialization for mx6ul_evk accordingly to fix the kernel hang issue at low bus frequency.
