Hi, I'm Luca,
I've some issues using a PCIe Realtek Ethernet board:
re0@pci0:3:0:0: class=0x020000 card=0x012310ec chip=0x816810ec rev=0x0c hdr=0x00
vendor = 'Realtek Semiconductor Co., Ltd.'
device = 'RTL8111/8168B PCI Express Gigabit Ethernet controller'
class = network
subclass = ethernet
bar [10] = type I/O Port, range 32, base 0x1000, size 256, enabled
bar [18] = type Memory, range 64, base 0x90500000, size 4096, enabled
bar [20] = type Prefetchable Memory, range 64, base 0x90400000,
size 16384, enabled
cap 01[40] = powerspec 3 supports D0 D1 D2 D3 current D0
cap 05[50] = MSI supports 1 message, 64 bit
cap 10[70] = PCI-Express 2 endpoint IRQ 1 max data 128(128) link x1(x1)
speed 2.5(2.5) ASPM disabled(L0s/L1)
cap 11[b0] = MSI-X supports 4 messages
Table in map 0x20[0x0], PBA in map 0x20[0x800]
cap 03[d0] = VPD
ecap 0001[100] = AER 1 0 fatal 0 non-fatal 0 corrected
ecap 0002[140] = VC 1 max VC0
ecap 0003[160] = Serial 1 01000000684ce000
ecap 0018[170] = LTR 1
Rx and Tx don't work. After some minutes the interface is activated I
get kernel panic.
I've already tried to disable MSIx and MSI.
It seems a DMA problem, rx fill the 256 descriptors and the nothing
else until the panic. netstat -s shows now new packets.
I filled a bug report with more infos:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197535
could someone kindly pointing some ideas?
Best regards,
Luca
