The in-tree realtek 5G/10G driver picks the firmware patch table from the
PHY ID (RTL8264 -> rtl8264b.bin). The vendor driver instead picks it from
VEND1 0x104[2:0] (0 = RTL8264B, else RTL8261N-C), independent of PHY ID.
On the S1300WP the RTL8264 dies read 0x104=0xf802 ([2:0]=2), so they need
the RTL8261N-C table; the RTL8264B table leaves the PCS unlocked (0xA600
stuck 0x1000) and config_init fails with -ETIME. Read 0x104[2:0] and load
rtl8261n.bin when non-zero. Boards with such a die must ship rtl8261n.bin.
