de95a4c5bb r8126: Fix PCIe completion timeouts 
During PTP operation, abnormal interrupt handling could stall internal
transactions, leading to delayed BAR register reads and PCIe completion
timeout errors.

This patch adjusts the PTP interrupt mechanism to
eliminate the stall and reduce latency.

cd7b169ce8 rtl8852ce: Add v126-10 to fix disconnect with new channel 
Issue - When WiFi operating channel is switched, at times the wifi
role index and role bitmap show that there is already a role
assigned for the channel context and this causes a failure in association. Kernel warning is shown when this occurs.

Fix - Update driver to v126-10 that fixes this issue.

97c57036d7 r8126: Disable LTR_EN in PCIe DevCtl2 register during probe 
Problem:
- When a Downstream Port Containment (DPC) software trigger is issued, the LTR_EN bit in the Root Port (RP) is cleared as per PCIe spec.
- However, LTR_EN bit of RTL8126 endpoint (EP) which is being expected to reset is still active and sends Latency Tolerance Reports (LTR) to RP.
- This behavior violates the PCIe spec, as LTR_EN is a non-sticky bit and should be cleared automatically on reset.
- As the RP has LTR disabled but the EP still sends LTR messages, it results in Unsupported Request (UR) errors on the RP.
- These UR errors trigger AER (Advanced Error Reporting) recovery, which includes a Secondary Bus Reset (SBR).
- The SBR causes the PCIe link to go down and come back up, but the EP again starts sending LTRs, leading to a infinite error-recovery loop.

Workaround:
- As a temporary fix, disable the LTR_EN bit in the RTL8126 EP during its probe.
- This prevents the EP from sending LTR messages, thereby avoiding UR errors and breaking the loop of AER recovery.

Impact:
- Disabling LTR prevents the EP from entering the L1.2 low power state.
- However, ASPM is currently not enabled in the system, so this workaround has no impact.

a59a10dfeb drivers: Update timer APIs for Linux v6.15 
In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.

11843f9878 nvethernet: fix Tx-ring full issue 
Issue: Below issue observed while running TCP_TX perf test
for longer duration.

nvethernet a808a10000.ethernet: [validate_ctx][1082][type:0x2][loga-0x84d2] dma_txrx: Invalid frame len
nvethernet a808a10000.ethernet mgbe0_0: Tx ring[0] is full
nvethernet a808a10000.ethernet mgbe0_0: Tx ring[0] is full
nvethernet a808910000.ethernet eqos_0: Tx ring[0] is full

This is a regression due to the below change -
https://git-master.nvidia.com/r/c/linux-nv-oot/+/3258684

The issue is that TSO packet is being treated as Non-TSO packet.
pskb_expand_head return code is returned directly where it can
return zero for TSO packet.

Fix:
Removed pskb_expand_head since headers are not getting updated in SW.
HW takes care performing the TSO handling. Also optimized the checks
in TSO path code.

In Linux v6,15, a 'speed' argument was added to the phy_loopback()
function. Add a conftest test to detect this change and update the
nvethernet driver accordingly. Note that if 'speed' is set to 0 when
calling phy_loopback(), then phy_loopback() behaves the same way as it
did before this argument was added. So by default set speed to 0 for the
nvethernet driver.
