Hello <div>I used gdb serial debug gpxe1.0.1 in my board lan rtl8111b. I used undionly for boot file . After PXE ,Ctrl_B break in the gpxe shell ,used autoboot for debug.In the debugger ,I set some breakpoints, such as dhcp_tx, dhcp_rx_offer, ipv4_tx. It could break in dhcp_tx after dhcp net0(XXX).</div>
