hello,
until 15 minutes ago I had a nasty ethernet behaviour on my laptop,
i.e watchdog timeout forever and ever in tx (rx seems ok for what I can see)
I decided to dig into the source and I've enabled a little bit of
degugging messages.
mskc0 at pci1 dev 0 function 0 "Marvell Yukon 88E8036" rev 0x13
begin mskc_attach
mskc_attach: allocate interrupt
mskc_reset
mskc_reset: sk_csr=4a
mskc_reset: sk_link_ctrl=2
mskc_attach: ramsize=4096 (4k), rboff=0
, Yukon-2 FE (0x1): apic 2 int 16 (irq 7)
msk0 at mskc0 port A
begin msk_attach: port=0, address 00:13:a9:60:1b:eb
msk_attach: rx_ramstart=0 rx_ramend=0x154
tx_ramstart=0x155 tx_ramend=0x1fe
first thing I've noted is the rx and tx buffer dimension calculation
rx -> 0x154
tx -> 0xa9
w/o thinking twice with a priory knowledge of ramsize i.e 4k
I've modified the algorithm as follow:
chunk = sc->sk_ramsize - (sc->sk_ramsize>>1);
val = sc->sk_rboff / sizeof(u_int64_t);
sc_if->sk_rx_ramstart = val;
val += (chunk / sizeof(u_int64_t));
sc_if->sk_rx_ramend = val - 1;
chunk = sc->sk_ramsize - chunk;
sc_if->sk_tx_ramstart = val;
val += (chunk / sizeof(u_int64_t));
sc_if->sk_tx_ramend = val - 1;
compiled and restarted:
mskc0 at pci1 dev 0 function 0 "Marvell Yukon 88E8036" rev 0x13
begin mskc_attach
mskc_attach: allocate interrupt
mskc_reset
mskc_reset: sk_csr=4a
mskc_reset: sk_link_ctrl=2
mskc_attach: ramsize=4096 (4k), rboff=0
, Yukon-2 FE (0x1): apic 2 int 16 (irq 7)
msk0 at mskc0 port A
begin msk_attach: port=0, address 00:13:a9:60:1b:eb
msk_attach: rx_ramstart=0 rx_ramend=0xff
tx_ramstart=0x100 tx_ramend=0x1ff
now both rx and tx buffer has the same size
result: msk works like a charm with no more watchdog timeouts
hope in a answer,
thanks,
