Wrong cubeMX limits for ETH DMA RX TX descriptors for STM32N6

Hello,

Descriptor limits is wrong, I found what in ST network examples the RX TX descriptor address is set at lower regions, but cubeMX does not allow to set to lower than 0x3410000, limit is at 0x34100000, everything is work without problems in D1 ram on N6, I need more ram and set at lower address, I ques this limit is related to H7 and maybe others MCU's, for N6 the limits is different.
