Series hw/net/xilinx_ethlite: Map RAM buffers as RAM and remove tswap() calls | expand

Commit Message

Philippe Mathieu-Daudé Nov. 14, 2024, 9 p.m. UTC 
Rather than accessing the registers within the mixed RAM/MMIO
region as indexed register, declare a per-port TX_GIE. This
will help to map the RAM as RAM (keeping MMIO as MMIO) in few
commits.

Previous s->regs[R_TX_GIE0] and s->regs[R_TX_GIE1] are now
unused. Not a concern, this array will soon disappear.
