2020-07-17net: atlantic: align return value of ver_match function with function nameMark Starovoytov1-1/+1
This patch aligns the return value of hw_atl_utils_ver_match function with its name. Change the return type to bool, because it's better aligned with the actual usage. Return true when the version matches, false otherwise. Signed-off-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.

2020-03-02net: atlantic: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Depending on FW configuration we can manage from 0 to 3 PINs for periodic output and from 0 to 1 ext ts PIN for getting TS for external event. Ext TS PIN functionality is implemented via periodic timestamps polling directly from PHY, because right now there is now way to receive the PIN trigger interrupt from phy.

L2 EtherType filters allows to filter packet by EtherType field or both EtherType and User Priority (PCP) field of 802.1Q. UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That is to distinguish VLAN filter from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID are passed in the same 'vlan' parameter. Example: To add a filter that directs IP4 packess of priority 3 to queue 3: ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \ action 3 loc 16 Signed-off-by: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

That is to distinguish VLAN filter from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID are passed in the same 'vlan' parameter. Flow type may be any as it is not matched for VLAN filter. Due to fixed order of the rules in the NIC, the location 0-15 are reserved for vlan filters.
