[gPXE-devel] gPXE is not support RTL8111B?

[kun zhu]

Hello
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).
Debug info:

Continuing.
Only break in xx_tx,but not break in xx_rx. I used wireshark  in  the server
to moniter, found 4 times dhcp disocver and dhcp offer, and then timeout.
Those debug infos are enough. Give some ideas for help me, thanks.
