Subject: [PATCH 01/13] be2net: do not modify PCI MaxReadReq size
|
||||
|
||||
commit 0513ac3d2212072c6694430b1003ad4246a35466 upstream.
|
||||
|
||||
Setting the PCI MRRS to a value of 4096 (overriding the system decided
|
||||
value) had provided perf improvement in TX.
|
||||
But, IBM has provided feedback that on POWER platforms, this value is set
|
||||
by the system firmware, and drivers modifying this value can cause
|
||||
unpredictable results (like EEH errors.) So, backing off this change.
|
||||
On POWER7 platforms most slots, it seems, do get a MRRS of 4096.
|
||||
|
||||
This patch reverts the following commit:
|
||||
"be2net: Modified PCI MaxReadReq size to 4096 bytes"
|
||||
commit 5a56eb10babbcd7b3796dc3c28c271260aa3608d.

|

|
||||
commit d79c0a207aa3be002e1d9473ea98cc4f838e5a8b upstream.
|
||||
|
||||
The CUST_SCRATCHPAD_CSR register is used for marking if FW cleanup is
|
||||
needed. This is used in a crash kernel scenario. Do no use this register as
|
||||
it is not available for some functions. Instead, always issue an FLR when
|
||||
a function is probed *except* when VFs are preset (enabled in the previous
|
||||
PF load).

Subject: [PATCH 08/13] be2net: Fix to trim skb for padded vlan packets to
|
||||
workaround an ASIC Bug
|
||||
|
||||
commit 93040ae5cc8dcc893eca4a4366dc8415af278edf upstream.
|
||||
|
||||
Fixed spelling error in a comment as pointed out by DaveM.
|
||||
Also refactored existing code a bit to provide placeholders for another ASIC
|
||||
Bug workaround that will be checked-in soon after this.

|

commit e8efcec5394cbf7ae67ccb137cb1a45ae3e6f6c8 upstream.
|
||||
|
||||
ETH_P_IP is host Endian, skb->protocol is big Endian, when
|
||||
compare them, we should change ETH_P_IP from host endian
|
||||
to big endian, htons, not ntohs.

|

commit ac1ae5f33fd225f46da0072e2091962410a0431b upstream.
|
||||
|
||||
skb_fill_rx_data() pulls 64 byte of data in skb->data
|
||||
|
||||
Its too much for TCP (with no options) on IPv4, as total size of headers
|
||||
is 14 + 40 = 54
|
||||
|
||||
This means tcp stack and splice() are suboptimal, since tcp payload
|
||||
is in part in tcp->data, and in part in skb frag.

by reenabling IRQ before calling ->poll, but it seems more
|
||||
problems are introduced after that patch:
|
||||
|
||||
http://ozlabs.org/~akpm/stuff/IMG_20120824_122054.jpg
|
||||
http://marc.info/?l=linux-netdev&m=134563282530588&w=2
|
||||
|
||||
So it is safe to fix be2net driver code directly.
|
||||
|
||||
This patch reverts the offending commit and fixes be_poll() by
|
||||
avoid disabling BH there, this is okay because be_poll()
|
||||
can be called either by poll_napi() which already disables
|
||||
IRQ, or by net_rx_action() which already disables BH.
