Subject: intel i40e buggy driver question
Hi
I have many problems with 40e driver
memleaks , kernel panics , stack traces , tx hungx , tx timeouts and
many many others :)
But the main problem that can't be resolved in linux is resolved in freebsd
problem in freebsd with this:
[2501243.181829] i40e 0000:01:00.1 eno2: VSI_seid 390, Hung TX queue 17,
tx_pending_hw: 1, NTC:0x16b, HWB: 0x16b, NTU: 0x16c, TAIL: 0x16c
[2501243.181835] i40e 0000:01:00.1 eno2: VSI_seid 390, Issuing force_wb
for TX queue 17, Interrupt Reg: 0x0
Was solved by this:
"
change this piece in ixl_tso_detect_sparse() in ixl_txrx.c:
if (mss < 1) {
if (num > IXL_SPARSE_CHAIN)
return (true);
num = (mss == 0) ? 0 : 1;
mss += mp->m_pkthdr.tso_segsz;
}
to
if (num > IXL_SPARSE_CHAIN)
return (true);
if (mss < 1) {
num = (mss == 0) ? 0 : 1;
mss += mp->m_pkthdr.tso_segsz;
}
Intel FreeBSD Team: This will definitely prevent MDDs on the buffers you
sent me.
"
An I have a question - how to do the same in linux ? :)
Cause i have same problem in Linux with this i40e buggy driver:
