2020-04-27aquantia: Fix the media type of AQC100 ethernet controller in the driverRichard Clark1-1/+1
The Aquantia AQC100 controller enables a SFP+ port, so the driver should configure the media type as '_TYPE_FIBRE' instead of '_TYPE_TP'.

2020-04-02net: atlantic: fix missing | operator when assigning rec->llcColin Ian King1-1/+1
rec->llc is currently being assigned twice, once with the lower 8 bits from packed_record[8] and then re-assigned afterwards with data from packed_record[9]. This looks like a type, I believe the second assignment should be using the |= operator rather than a direct assignment.

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.

Artificial HW reliability tests revealed a possible hangup in the driver. Normally, when device disappears from bus, all register reads returns 0xFFFFFFFF. At remote procedure invocation towards FW there is a logic where result is compared with -1 in a loop. That caused an infinite loop if hardware due to some issues disappears from bus.

2020-02-16net: atlantic: checksum compat issueDmitry Bezrukov3-4/+7
Yet another checksum offload compatibility issue was found. The known issue is that AQC HW marks tcp packets with 0xFFFF checksum as invalid (1). This is workarounded in driver, passing all the suspicious packets up to the stack for further csum validation. Another HW problem (2) is that it hides invalid csum of LRO aggregated packets inside of the individual descriptors. That was workarounded by forced scan of all LRO descriptors for checksum errors. However the scan logic was joint for both LRO and multi-descriptor packets (jumbos). And this causes the issue. We have to drop LRO packets with the detected bad checksum because of (2), but we have to pass jumbo packets to stack because of (1). When using windows tcp partner with jumbo frames but with LSO disabled driver discards such frames as bad checksummed. But only LRO frames should be dropped, not jumbos. On such a configurations tcp stream have a chance of drops and stucks.

2019-11-13net: atlantic: Signedness bug in aq_vec_isr_legacy()Dan Carpenter1-1/+1
irqreturn_t type is an enum and in this context it's unsigned, so "err" can't be irqreturn_t or it breaks the error handling. In fact the "err" variable is only used to store integers (never irqreturn_t) so it should be declared as int. I removed the initialization because it's not required. Using a bogus initializer turns off GCC's uninitialized variable warnings. Secondly, there is a GCC warning about unused assignments and we would like to enable that feature eventually so we have been trying to remove these unnecessary initializers.
