Re: [PATCH 1/1] AX88179_178A: Add FLAG_HW_IPALIGN to determine whether reserving NET_IP_ALIGN bytes for an SKB.

David 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?

David 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

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.

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? -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH resubmit] ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver
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
This is a resubmission. 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.
