The ath9k NIC driver is used here, the hardware platform is Tp-link tl-wr841n V7.1 Router 1 ath_pci_init ()The main entrance of the drive is Ath_pci_init () (in the Pci.c file under the linux-3.3.8/drivers/net/wireless/ath/ath9k folder):
int ath_pci_init (void)
{
return pci_register_driver (ath_pci_driver);
}You can see that Ath_pci_driver is passed as a parameter to Pci_register_driver (). The ath_pci_driver is defined as follows (in the Pci.

Notes for upgrading the IOS version of CiscoASA Firewall
Reference the official Cisco announcement:
Vulnerability in Internet Key Exchange (IKE) Version 1 (V1) and IKE Protocol Version 2 (v2) the Cisco ASA software code may allow unauthenticated remote attackers to reinstall the system or execute code remotely.
This vulnerability is caused by a buffer overflow in the affected code zone. Attackers can exploit this vulnerability to exploit this vulnerability by sending specially crafted UDP packet

devices have the same name as their plugins, but some devices do not. Sometimes different ALSA devices use the same plugin. Therefore, in this section, we will give the name of each plugin. If possible, we will also give the names allowed by specific hardware devices to use this plugin.
The most important plug-in is HW plug-in. It does not process itself, but only accesses the hardware driver. If the application selects the PCM parameter (sampling ra

The result shows that there is a read operation problem here.Test function (){HW write operation;HW read operation;Compare read/write data;}After analysis, we found that as long as there is a little delay in the middle, the read operation is OK.

In the previous article, we put the user's request response logic in the routing process, in fact, this is not realistic, and there is no front code so simple.
In most cases, the user's request action is handled in the controller (this does not include the business processing logic).
All controllers in the Laravel are in the App/http/controllers directory.
