Thanks for your advice.
In the way you advised, does the dev->skb_align equal
to NET_IP_ALIGN in the case that HW doesn't supoort
IP alignment?
In other words, dev->skb_align should be initialized to
NET_IP_ALIGN in USBNET, and I can change its value to
0 in AX88179_178A driver, right?

Given the definition:

*dev,
 unsigned int length, gfp_t gfp)
{
 struct sk_buff *skb = __netdev_alloc_skb(dev, length + NET_IP_ALIGN,

 if (NET_IP_ALIGN && skb)
 skb_reserve(skb, NET_IP_ALIGN);
 return skb;
}

It really ought to be possible to code that without an extra conditional.

The AX88179_178A driver do need to know the value of NET_IP_ALIGN
to determine whether enabling the feature that makes IP header align
on a dword-aligned address, but according to the comments from David
Miller, I need to consider all situations, not just for the case that
NET_IP_ALIGN is zero, so the condition added in rx_submit is just used to
determine whether reserving NET_IP_ALIGN bytes for each SKB.

Re: [PATCH 1/1] AX88179_178A: Enable the hardware pseudo header in case of the NET_IP_ALIGN equals 0

From: Freddy Xin 

The AX88179_178A has a hardware feature that it can insert a 2-bytes pseudo
header in front of each received frame by setting the AX_RX_CTL_IPE bit.
This feature is used to let the IP header be aligned on a doubleword-aligned 
address,
but the NET_IP_ALIGN may equals to 2 and the __netdev_alloc_skb_ip_align in 
USBNET will
reserve 2 bytes also, so in this case the driver shouldn't enable this bit.

This patch modifies the driver to set AX_RX_CTL_IPE just in case of the 
NET_IP_ALIGN equals 0.

Signed-off-by: Freddy Xin 

Please avoid larger than 80 column lines in your commit messages,
people use text-only tools to viee these.

Next, it makes no sense to restrict your change to NET_IP_ALIGN==0

Simply handle any case, by undoing the reservation if it's getting
in the way.  If there isn't an appropriate helper for this, add one.


I think there is no way of undoing the reservation in the driver.
Can I add a flag of the driver_info, and use it to determine
whether undoing the reservation in rx_submit of usbnet?

[PATCH resubmit] ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver

2013-03-02 Thread Freddy Xin
From: Freddy Xin 

This is a resubmission.
Added kfree() in ax88179_get_eeprom to prevent memory leakage.
Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed 
pointless casts.
Removed asix_init and asix_exit functions and added 
"module_usb_driver(ax88179_178a_driver)".
Fixed endianness issue on big endian systems and verified this driver on iBook 
G4.
Removed steps that change net->features in ax88179_set_features function.
Added "const" to ethtool_ops structure and fixed the coding style of 
AX88179_BULKIN_SIZE array.
Fixed the issue that the default MTU is not 1500.
Added ax88179_change_mtu function and enabled the hardware jumbo frame function 
to support an
MTU higher than 1500.
Fixed indentation and empty line coding style errors.
The _nopm version usb functions were added to access register in suspend and 
resume functions.
Serveral variables allocted dynamically were removed and replaced by stack 
variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.

This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.

[PATCH, resubmit] ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver

2013-01-22 Thread Freddy Xin
From: Freddy Xin 

This is a resubmission.
Fixed coding style errors.
The _nopm version usb functions were added to access register in suspend and 
resume functions.
Serveral variables allocted dynamically were removed and replaced by stack 
variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.

This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.
